I

am so thankful to be so kindly introduced. Having been asked to talkas simply as possible, I would like to explain the basic teachings ofIslam them here today.

1. Japanese views on religion and Islam
First, I would like to talk about Japanese views on religion and Islam.
As the word “Islam” is frequently heard on TV and in newspapers whenwars and terrors occurred, Islam tends to be easily associated with conflict and war. I suspect that most Japanese have such negative images ofIslam as troublesome or militant religion.
There are approximately 1.2 billion Muslims, namely one fifth of theworld’s population. Most of them, obviously, never support terrors andwars, but live their peaceful daily life today as well as in the past.
Though Islam fought with disbelievers in the very beginning, it soon
rapidly spread in a peaceful way, and coexisted with Jews and Christians
until 19th century. However, Japanese mass media have seldom covered
Islamic history and Muslims’ daily life, which may be to some extent
responsible for Japanese’ wrong image of Islam.
Though not a specialist, I have considered what Japanese religions arewhile comparing Islam with them. I have come to believe that Japanesepeople generally dislike monotheism and strict religious precepts. Thisview on religion would make, to some extent, it difficult for them toappropriately understand Islam. As for Christianity, another monotheism, as it had a smell of the western culture which Japanese longed forand admired in the Meiji period, many mission schools became popular.
Though many Japanese recently prefer wedding ceremonies in Christianchurches to those in traditional Shinto shrines, the number of Christians
has not increased in Japan. Ryotaro Shiba succinctly spoke that Christianity did not recover its investments in Japan. In other words, though it
75

76

spent huge donations for establishing missionary schools, it has not succeeded in raising the number of Japanese Christians. Most Japanese
have never stopped their ancestor worship, while they have venerated
Buddha and other various gods. This would be a reason why Japanesepeople dislike monotheisms including Christianity, which order not toworship ancestor and other gods than the one true God.
As for the religious precepts, while some Buddhist monks lead strict
ascetic lives at several temples, Japanese Buddhism never has imposed
strict precepts on lay Buddhists. At the most, to eat meat and fish wastaboo during the Buddhist funeral, but now it is not uncommon to findsashimi being served. Shinto has not had strict precepts concerning daily
life. Thus, as the Japanese people have not got accustomed with religious precepts throughout their history, the Islamic prayer five times a
day is enough to make them shiver. By contrast, as Muslims are raised
in a society where almost all people daily observe religious precepts,
they grow and naturally observe such precepts without serious doubt.
Probably influenced by Buddhism, many Japanese suppose that religion is related to death and disease. One becomes religious only when
one suffers disease and misfortune, and otherwise, one needs no religion. Oddly enough, though few Japanese Buddhist monks haverenounced the world in a full sense, many Japanese tend to consider thatthe religious life should be in the withdrawal from the world. Consequently, though most Japanese, both lay Buddhists and Shinto believers,
perform ceremonies for the dead, including visit to ancestor’ tomb, andalso participate in seasonal rituals at local Shinto shrines such as New
Year’s rite (Hatsumoude), they identify themselves with no religion.
Muslims could hardly understand these Japanese views of religion.
Islam stresses on Muslim’s social life, teaching that death or disease iscaused by God’s decree, and as a result, it is rather indifferent to deathand disease. Islam is, so to speak, a religion of those who spend healthysocial life, and Muslims should be religious in their family life and economic activities. Compared with Islam, it becomes clear how greatly
different Japanese views of religion are from the Muslims’.
Japanese people hardly feel any contradiction when they say that
Christianity and Islam have respectively their own only one god. However, the only one god in a monotheistic sense means that all other gods
but the one are false gods, which should be destroyed. Logically speaking, a new monotheism should either deny the gods of old monotheisms
or recognize them as the same one god of its own with different names.
In relation to Japanese religions, any monotheism never allows to worship ancestor and other gods. It performs the memorial service for theTHE BASIC TEACHINGS OF ISLAM

77

dead, but prohibits worship of them. So far as Japanese people stick toancestor worship, they are reluctant to convert to monotheism.

2. The Foundation and Spread of Islam
Islam is the third monotheism, following Judaism and Christianity. It isa world religion, spreading beyond a single ethnic group. Though theworld religion theoretically teaches any individual to convert, childrenof believers naturally accept the same faith of their parents once the religion is established. In this sense, the world religion becomes to someextent similar to ethnic religions.
Islam began at Mecca, in Saudi Arabia of today, which is the centerand the most sacred place of Islam. Islam calls the Arab tribal society
before of Islam Jahiliyyah, which literally means ignorance. This is aderogatory expression from the point of view of Islam, for it had had norevelation as the source of knowledge and morality. However, it was notcompletely barbaric, but the Arabs had their own tribal religion, moral
and laws. The religion of the Jahiliyyah period was of archaic religion,
and mainly worshipped ancestors and tribal gods. In other words, it waspolytheism, and quite similar to Japanese religion today. I sometimes
say that Japan still remains Jahiliyyah, when I explain Japanese religions to Muslims. While local gods protect their land in agrariansocieties of Japan, Arab tribal gods naturally protected the people
themselves, not their land, for most of the Arabs as nomads or caravan
traders moved around. While Buddhism has been deeply incorporated
in Japan, it did not ban Japanese worships of ancestor and local gods, sothese still survive in abundance. In polytheism, where we are surrounded by gods, we do not venerate every god in turn. While we worship ourown god, we do not mind if other gods exist. This is polytheism.
A prophet suddenly appeared and began to tell the Arabs of
Jahiliyyah that their gods were false so as to believe in the one true God.
As his teaching denied their traditional religion, it is not surprising thatthey could hardly believe in him, but mocked at him. This is exactly thesame way in which various new religions began. Not only Islam, but
Buddhism and Christianity too, when they first began, were merely
dubious new religions far from world religions. It was not obvious at
first whether Buddha or Jesus were the real man of faith or not. It is only
natural that most people regarded the founders as queer, saying others
that they should not follow them. Despite this, the first believers and disciples flew to them.
Generally, when a new religion begins, it is a kind of a religious ener-

78

THE BASIC TEACHINGS OF ISLAM

gy of its founder that makes people attract and convert. It is named thecharisma, which originates from God or the religious truth, and bestows
the religious authority on the revelation and founder’s personality. Without such a miracle power, it would be impossible to convert those who
felt satisfied with Jahiliyyah life style to a new monotheistic religion.
Islam began around 610 CE with Muhammad experiencing divine
revelation and becoming a prophet, and within approximately a hundredyears it spread over a vast area, from the Iberian Peninsula and Spain in
the west to the Middle East in the east. Having its origins as the religionof Arabian merchants, this expansion increased along the fringes of theMediterranean Sea and Silk Road trade routes.
Various empires rose and fell one after another in the Islamic world.
The most famous in the Middle East are probably the Umayyad dynasty,
the Abbasid dynasty, the Ottoman Empire of Turkey and the Safavid
dynasty of Iran. In India too, an Islamic state known as the Mogul
Empire was temporarily founded. The reason why Pakistan and
Bangladesh today are of Islamic countries is due to the fact that, during
the Mogul Empire period, many Indians converted to Islam. When India
gained the independence from Britain, Hindus and Muslims divided andbecame independent as separate countries, despite being the same ethnic
people.
The center of the modern Islamic world is of course the Middle East.
Islam spreads among African countries. Many Muslims lived in Central
Asia before the coming of the Soviet Union which banned any religion.
After the Soviet Union collapsed, the past faiths, to be surprised, haverevived, namely Islam in the Central Asia, and Russian Orthodoxy inmost parts of Russia.
As for the South East Asia, the population of Muslim is high inIndonesia and some part of Malaysia. Since early Islamic period, there
have been Muslims in Central Asia, western part and also Fujian
Province in China as results of trade relations with the Middle East.
Additionally, there are quite a number of Black Muslims in America, of
which the heavy-weight boxer Muhammad Ali, formerly known as Cassius Clay, is well known. As for Europe, there are many Muslims
amongst immigrants there, in relation to whom one may remember thatriots occurred in 2005 in France. The immigrant population is growing,with many immigrants from the old African colonies in France andthose from Turkey in Germany, which has caused some economic andpolitical problems in one way or another. There are not so many Muslims in Japan, but Muslims live all over the world, and one-fifth of theworld’s population, one out of five people, is a Muslim. Therefore, it isTHE BASIC TEACHINGS OF ISLAM

79

extremely important to have dialogue between Buddhism and Islam. It is
one of the religions which Japanese must actively learn more about.
Since the Crusaders were defeated by Islam, Christians in Europe
have seldom held good impressions of Islam, and instead, prejudice hasremained in Europe towards Islam. For even great scholars such as
Hegel and Weber viewed Islam in distorted ways. That alone is probably
proof enough of Europe’s deep prejudice. It seems that today’s Americans are dragging the similar prejudice, but I would like to touch a little
upon some current issues at the end.

3. The Prophet Muhammad and the Qur’an
The word “Islam” means submission, which is same as “Nam” in “Nammyoho renge kyo” and “Nam amida butsu.” Its believer is called Muslim(Muslima, for female believer), literally meaning “a person devoted to
Allah.” Allah is the one true God of Islam, and Muhammad is his
prophet, who used to be called Mohamet in western languages. He wasborn at Mecca around 570 CE, and died in 632 CE. He was a merchantof caravan before he became a prophet about 40 years old.
The Qur’an, meaning what should be recited, is the basic sacred bookof Islam. As each sentence of the Qur’an is called verse, it sounds poetically when it is recited. Its recitation is often heard from mosques at
every corner of cities or on broadcast. As idols are strictly prohibited,
there is no statue or image of God in mosque. It is very simple spacewith nothing but a mark to point out the direction of Mecca. The world
religions generally forbid to create visual representations of God, suchas images, statues, sculptures and pictures. However, once created, statues of Buddha have been accepted and widely spread, despite the belief
that Buddha has no name or image. It is almost same case with Christianity. However strictly the theologies prohibit idols, they are necessary
for ordinary believers to sensuously see and feel the existence of God or
Buddha. In Islam, the recitation of the Qur’an plays the same function
as images of god in other religions, for the recited words of Allah vividly remind Muslims of God.
According to Islam, the Qur’an is nothing but the words which God
himself revealed in Arabic. Each time receiving a revelation, Muhammad related it to Arabs without any modification. Of course, they heard
it through Muhammad’s voice. Those who heard it as merely Muhammad’s words remained disbelievers, but only those who could hear it as
the authentic God’s revelation became Muslims. For Muslims, theQur’an holds the words directly spoken by Allah in Arabic, in other80

THE BASIC TEACHINGS OF ISLAM

words, the author of the Qur’an is God himself. The Qur’an is so sacredthat Muslims became angry and furious when it was insulted or broken.
Because the prophet Muhammad never became a living god, thewords he told to his friends and family were not God’s words. The
words of God, namely the Qur’an, were carefully distinguished from
Muhammad’s words. Probably when Muhammad conveyed revelations,
he might have paid attention to revelations. Muhammad’s sayings anddeeds were first kept in memory of his intimate followers, and gradually
recorded in the Hadith (Tradition) after Muhammad died, separated
from the Qur’an.
Christians have sometimes misunderstood the sacredness of the
Qur’an. In Christianity, Jesus Christ is the incarnation of Logos of God,and the New Testament mostly consists of words and letters of Jesus’
disciples. In a sense of the primal locus of divine self-manifestation, theQur’an in Islam, not Muhammad, should be equated to Jesus Christ in
Christianity. This is a key point to rightly understand Islam. In addition,
mentioned below, Muhammad could not play the role of savior like
Jesus Christ, which is the reason why no priesthood or the church as theinstitution of priests was not brought forth.

4. The World View and Contents of the Qur’an
The Qur’an is made up of 114 chapters. While each chapter has a title,
the title does not symbolize the theme of the chapter. As each chapter
contains various topics, the above-mentioned major topics such as theCreation are repeatedly referred to in many chapters. Diagram schematically disposes major themes of the Qur’an in a chronological order. It
also shows the Qur’anic world view, beginning with the creation of thisworld, destruction of it and bringing forth of the Hereafter.

The Qur’an describes several different ways of Creation. First, God
created the world from Nothingness just like in the Old Testament(2:117, 7:54 and so on); secondly He divided Heaven and Earth from theprimordial chaos, then the seas from mountains. In any way, God created the whole world and all kinds of creature including mankind, and has
ever maintained the natural order such as regular exchange of day andnight (35:13). Human beings have already enjoyed God’s Mercy so far
as they live, for whatever they eat is ultimately brought up on God’s
Earth. Nevertheless, they forgot God and thankfulness to Him, and havebrought disorder on His earth by means of wrong deeds.
Next, there is a group of stories about the prophets in the past. As
mentioned above, from the standpoint of the third monotheism Islam,both Judaism and Christianity received the revelations or the Bibles
from no god but Allah, the same one God. This Islamic view is similar
to Christianity which incorporated the Jewish Bible as the Old Testament, besides the New Testament. The Qur’an states that the same Allah
sent Jewish prophets and Jesus with the originally same revelations(5:68–82). Of course, Jews and Christians absolutely denied this, andpointed disparities of teachings. According to the Qur’an, such differences occurred because Jews and Christians willfully abandoned or distorted the revelations. Islam recognizes Jesus as a prophet, but neveradmits him as the Son of God, stating that it is unthinkable that God hada child (2:116). Since Jesus Christ is the most sacred mysterious truth inChristianity, it seems impossible that Christianity allows the Islamicinterpretation on Jesus. In the Qur’anic context, the stories of the previous prophets which tell how they and their revelations were rejected bypeople encouraged Muhammad and his faithful followers persecuted by
Arabs of Jahiliyah (7:101 onwards).
The Qur’an mentions nothing about future events in the world history
after Muhammad but the Last Judgment. If one produces a movie basedon the Qur’anic stories which are described with vivid images, a sceneof Muhammad’s era suddenly skips to the eschatological one. It starts
with blast of angel’s trumpet, and the whole cosmic order begins to beutterly destroyed; the stars fall, the earth splits and melts, mountains arescattered like cotton and the sea boils (chapters 81–82). Then the Last
Judgment will be held, as similarly taught in Christianity. All men haveto be brought forth to the Judgment, and confront with Allah. No one
can get rid of it. As soon as the world ends, the dead are brought back tolife by God only to receive His Judgment. All who believed in thisworld will go to Heaven, but those who did not will go to Hell (69:18).
The Qur’an describes so concretely and realistically attitudes and82

THE BASIC TEACHINGS OF ISLAM

reactions of men in the scene of the Judgment that its keen observationof human nature surprises us. It also depicts attitudes and reactions ofmen in scenes of the Judgment; for example, some try to pretend to be abeliever, some deplore their careless life, others are just surprised at, or
gladly accept God’s fair judgment (37:14–33).
Since the idea of Eschatology was not found in Jahiliyyah religion,
Arabian people of Jahiliyyah most radically rejected the resurrection of
the dead among the Qur’anic teachings (34:3–8). People asked Muhammad how the dead could rise from the earth. He only answered that hedid not know, but also that it would definitely happen because God has
promised. As most Japanese people today do not believe in the Eschatology for a rational reason, Arabs of Jahiliyyah were rational in a sense.
Since disbelievers do not believe in the Hereafter, Hell does notfrighten them. The Qur’an depicts how much upset the disbelievers at
the moment of the Last Judgment. According to the Qur’an, some disbelievers wish to convert to Islam as soon as the eschatological moment
begins, but such conversion will not be approved. Dragged before God,
they have to recognize what their life was, based on the record book of
their life, which records whole life in detail, even the most minor deed.
One of the most impressive descriptions related to the Judgment is asfollows: man tries to deny his sins such as beating or kicking the others
even in the Judgment, so God allows man’s skin and limbs to speak oftestimony, which begin to testify his kicking (41:20–22). This depiction
teaches us that the body is really nothing but a part of man’s self, though
man especially in modern era tends to consider the self-identity only interms of consciousness. The Qur’anic descriptions on the Last Judgmentimply that it is the only chance when everyone recognizes the true
dimension of one’s own life. So far as man usually interpretatively
understands his doings or sayings from his own intention and perspective, ignoring others’ reactions, he does not always know the truth of hislife.
The Qur’an depicts men’s conversations in Heaven and Hell, which
are so humanistic and ordinary that it would be hard to imagine that they
reside in the eternal spiritual worlds. Believers enjoy the eternal life in
Heaven with thankfulness, saying that they were lucky to have become
believers without any clear reason for faith. By contrast, men in Hell are
ever burning, wail and blame each other for their lack of faith (34:31–
34). At a first glance, these descriptions may sound strange, but the
Qur’an well teaches us that it is just ordinary people as ourselves whowill reside in either Heaven or Hell. Viewed in this way, the Qur’anic
depictions are full of keen insight into human being and as such quiteTHE BASIC TEACHINGS OF ISLAM

83interesting.
Above-mentioned major themes in the Qur’an explain why we mustbelieve in Allah, who God is, what mankind is, what the Eschatology,
the Last Judgment and the Hereafter will be. In a word, they tell the one
theme, the invitation to faith, from different perspectives. The Qur’ancontains both good news, the promise of Paradise, and the warning ofHell. Let us consider how the Qur’anic descriptions function in themechanism of conversion from Jahiliyyah into Islam. The people of
Jahiliyyah first heard revelations fictional, but gradually converted. Let
us liken the Qur’an to a movie again, they were forced to watch themovie against their will. They first considered the Qur’anic stories to bea fictional movie, then some of them who believed that the world of
Jahiliyyah was the real naturally regarded them as a movie, while theothers began to think that the world of this movie might be the real, who
would become believers. This shows that the latter accepted the Qur’anic stories as the truth. The power which made them convert is the sacredauthority and power of the Qur’an, the words of God.
To the category of “revelations to Muhammad” in Diagram 1, othervarious topics than what are mentioned above belong. Here is considerable number of rituals and social precepts, which developed to the
Shari’ah, Islamic legal system, a few centuries later. Besides, God consoles and encourages Muhammad and his followers who suffered bybattles with disbelievers of Jahiliyyah.
Let us explain the Qur’anic views on human beings and their sins,
which help to understand why Islam stresses the Shari’ah. As God creates human beings as the synthesis of soul and body, even believers cannot get rid of the bodily existence, so they have sexual desire andappetite. Although Islam seems to be a very strict religion, it admits andtolerates physical desires. If Christianity emphasizes the spirituality bysaying that man should not live on bread alone, Islam puts as equalstress on the bodily existence as on the spirituality. Thus in Islam, thedomestic life and economic activities should not be despised, but of religious issues as parts of Muslims’ lifestyle. This is why social norms areincluded in Islamic precepts.
Unlike Buddhism, Islam does not require the renouncement, so every
Muslim is a lay believer. This is another reason why Islam imposes
many strict rituals. Since those who engage in daily social life can notalways concentrate on God, Islam teaches a Muslim to pray and concentrate on God only during praying time five times a day. After a prayer,
one can again continue his daily life. Japanese who do not get used to84

THE BASIC TEACHINGS OF ISLAM

strict religious precepts tend to think that such obligatory prayer is hard
to do, and also that it presupposes the self-power to attain to salvation
by man’s good deeds. Indeed, knowing that Islam does not admit theChristian idea of the original sin, a Japanese historian of religions asked
me many years ago if Islam is optimistic about human sinfulness. Since
then I kept considering an appropriate answer to his question.
My understanding of the Qur’anic concept of the human sinfulness is
as follows. The idea of the original sin is the self-awareness of sin, anddoes not mean any specific sin but the primal cause of various sins. The
karma in Buddhism may be somehow equivalent to the original sin, for
it is also considered as the cause of misfortunes or sins. Nishida Kitaro
states that the religious concept of evil is different from the ethical one,for the religious evil is inherent to everyone, even to a good holy man. If
it is so, the religious concept of evil can be interpreted as the humanfinitude because of which man actually commits sins. Islam also sokeenly points to the human finitude that it requests man to obey God.
Nevertheless, Islam does not admit the idea of original sin as well as
Judaism. Instead, the Qur’an enumerates many detailed rules concerning
to marriage, divorce, inheritance and so on. Most Japanese may be surprised at its detailed descriptions of troubles related to money and sex in
the sacred scripture. However, the fact that the Qur’an gives many rules
precisely means that it recognizes that mankind in general and even
Muslims tend to fight each other, and easily commit sins especially inthe above-mentioned cases. In this sense, Islam as seriously recognizes
the human sinfulness as Christianity does. Then, what does the difference mean? Since the original sin points to the primary beginning of evil
at the mythical past, Christianity seriously inquires why human beings
became sinful. Man’s sinfulness is forgiven only if man believes in Jesus
Christ who died on the cross to redeem mankind’s sin. Though the
Qur’an states the same myth of the Fall of Adam and Eve, it does notteach the original sin. According to it, God forgave Adam after heregretted his sin, but God expelled Adam and Eve from Paradise to theearth, where human beings forgot God and fought each other, just likethe people of Jahiliyyah. Even if the people of Jahiliyyah had forgotten
God and committed sins, those previous sins were forgiven at the
moment of their conversion to Islam. But, to remain a disbeliever after
hearing the revelation is the worst sin in Islam, which God will neverforgive.
Islam puts emphasis on the result of sins which will be clarified on
the Day of Last Judgment in the future, and warns disbelievers tobelieve, and believers not to commit sins. Only those who believe in theTHE BASIC TEACHINGS OF ISLAM

85

Last Judgment can realize how significant their trivial actions here andnow are, for it is their actions that will be judged by God and determine
the eternal residence. Most people usually commit trivial misdeeds ormalicious actions, but will soon forget them if bothering their conscience for a while. However much does Islam seem to be a this-worldly
religion because of its strong concern to man’s worldly life, Islam surelyis the other-worldly religion because all the worldly actions are always
stressed and evaluated from the eschatological dimension.
Related to the Qur’anic views of human beings, let us briefly explain
why Islam has no priesthood. Although there are theologians and jurists,they are scholars and do not have any special soteriological authority. Aseven the Prophet Muhammad was not a savior in a strict sense, no one
or institution logically could inherit the function of savior. So there hasneither been any mediator between God and lay Muslims, nor a church
as a heretical institution in Islam. The Islamic soteriology is nothing but
to believe in God and to observe the precepts, which is equally obligatory to all the Muslims, regardless of education, status and money. However, the Prophet Muhammad was yet a charismatic person as thefounder of Islam. He was the founder of the Islamic community(Ummah), and actually he did his best as a political and even militaryleader. Most Japanese may be surprised to hear that. However, because
Muhammad best understood what Islam should be, he tried to establish
the Ummah as the Islamic community of Muslims in history, including
its socio-political aspect. In a word, Islam is utterly different from Buddhism which basically recommends the renouncement from the sociopolitical life.

5. The Ummah and the Shari’ah
It is usually said that Islam has no division between church and state,
and indeed, it has never had any heretical center or institution such as
the Vatican. As the separation of state and religion is considered rationalin most modernized countries, Islam seems exceptional and hardly
understandable. This is one of the main reasons why the Westerners
have misunderstood and held prejudice to Islam for many centuries eventoday.
Though Islam has had no church, it stresses the significance of the
Ummah, the Islamic community. It has been, though not institutionalized, surely existent as a religious community in the Muslim world. In
the Qur’an, the expression “ummah muslimah” is used only once
(2:128), meaning a community of Abraham’s descendents which as a

86

THE BASIC TEACHINGS OF ISLAM

community itself will obey to God’s will. The Ummah is an integral religious community; it is no doubt a community of faith in the same senseof Christian church, but at the same time, a socio-political order where
Muslims live their daily life. It is on the Shari’ah only that the spiritualand social orders of the Ummah are based. Though relations of theChristian church to states changed in the course of history, it is, at least
theoretically, independent from state. Christians as well as most Buddhists live their social life in accordance with regional social rules andstate laws, somehow different from the religious. It is not easy for man
to live in accordance to two different principles. For example, Japanese
Christians since the Meiji era have probably experienced this difficultyin Japanese society, where traditional Japanese religions have beenstrongly influential. Japanese Christians who spiritually converted haveto keep following the Japanese social norms and family system. Though
Christianity forbids ancestor worship, they may confront with ancestor
worship, and have to choose either to discard it against majority’s
blames or to accept it against Christian teaching. Another example is a
Christian theologian living in Kyoto who takes part in a local festival of
Jizo-bon (a folk religious ceremony for children). This surprised me, but
it probably makes sense in order to live without conflict in a local community. Thus, Islam constructed an integral community from the beginning. However, it had to confront another difficulty, for the Shari’ah
could not be easily modified in accordance with social changes.
As earliest Muslims well understood the Islamic way of religious life,
they ignored their old tribal rules and customs of Jahiliyyah, andobserved Islamic social rules. Since the Ummah was established at Medina, Muslims needed various rules concerning both rituals and social
actions. During Muhammad’s lifetime, some rules were given by revelation, the others were decided by him. After his death, his close followers
continued to find new rules, which was the formative process of the
Shari’ah (see below). When Muslims became majority, those who
remained Jahiliyyah might be hard to get married and to continue theirbusiness with Muslims. So they would become Muslims. This would bea reason why Islam spread rapidly throughout the Arabian Peninsula.
Another reason why many Arabian Christians, though Jews did not,became Muslims would be related to Islamic taxation which imposedheavier tax on non-Muslims than Muslims.
Islam is so coherent religion that the people who converted to Islammust have found it comfortable to abide by. Let us briefly refer to IndianMuslims. There were few converts to Christianity in India, though the
Britain ruled over it for 300 years. On the other hand, many Indian peo-THE BASIC TEACHINGS OF ISLAM

87

ple converted to Islam, and today they live in Pakistan and Bangladesh.
Hinduism has a system of precepts called Hindu Dharma on which thecaste system is based. An Indian Christian would be hard to survive
there, for Christianity has neither admitted it nor offered alternative
rules of social life such as marriage and economic activities. Because
Buddhism took similar attitudes toward Indian caste society, lay
Buddhists might be difficult to live in the caste system. If so, it sounds
reasonable that Buddhism could not survive there. By contrast, IndianMuslims could observe the Shari’ah in cases of marriage and businesswithin Hindu caste society.
The Ummah itself is not a state, but a religious community whichlooks after both the spiritual aspect and social lives of Muslims. However, in order to maintain its social order, it needs the political power andjudicial sanction. As a result, the Ummah comprehends theoretically astate, or historically plural states, within itself.
It is well-known that Jesus Christ emphasized forgiveness, teaching
one who threw stones at prostitutes to forgive them. Of course, Jesus
recommended forgiveness based on his teaching of the original sin.
Besides, Jesus would do so because he did not wish to govern thisworldly social order. Forgiveness, which is very important in religious
ethics, is indeed recommended in the Qur’an too; for example, it ispreferable not to get back the betrothal money at the case of divorce, if
legally allowed. However, the social order can not be justly maintainedby forgiveness and conscience alone. Suppose how safely we could
drive a car without any traffic regulation but with the spirit of mutual
forgiveness. As society is made up of all kinds of individuals with various tempers and personalities, also different in moral, intellectual, physical abilities, we need laws and justice to keep rightly social order in
addition to mutual forgiveness and conscience. Law and justice will
punish those who transgress rules and injure the others. The fact that weneed laws and justice to maintain the social life may be interpreted as an
aspect of human weakness, fallibility, finitude and sinfulness in religious
sense. Since Islam recognizes the social life as an indispensable aspectof Muslim’s religious way of life, Islam developed the Shari’ah bymeans of which the holistic order of the Ummah would be maintained.
The Shari’ah is extremely important, and a correct understanding of
Shari’ah is necessary in order to understand Islam. As the Shari’ah is avery complex system of precepts, it is not easy to briefly explain its all
aspects. The following explanation is referred only to its religious significance and to some basic features. While Shari’ah is translated as“Islamic Law,” it originally means “a path leading to water place,”

88

THE BASIC TEACHINGS OF ISLAM

namely the path of life. Incidentally, as Buddhism has “the path of Buddha,” and Jesus said “I am the way,” the relationship between religion
and the concept of path seems interesting. As a path is a place where
man walks or treads, it somehow presupposes some kind of practice.
However, in Buddhism and Christianity, the concept means a spiritual
path, and is not articulated into many rules of conduct; it is left to individual faith and conscience how to act in accordance with the religious
spirit. Though the Islamic Shari’ah holds a meaning of the spirit ofdevotion, Islam articulates it into detailed rules of conduct, some ofwhich are found in the Qur’an. This is the system of laws, the Shari’ah
as a system of rules made of various precepts.
Many Japanese know Shinran’s teaching that ordinary men who cannot do ascetic practice will be saved only by belief in Amitabha Buddha.
This way of faith seems to be popular among Japanese people. Those
who think that one’s deep faith naturally leads to prayer consider it
unnecessary to make prayer obligatory, or dislike such coercion. Contrary to Shinran, Islam may consider that it would be difficult for ordinary weak men to keep deep faith without obligatory prayer. Rather, inorder to cultivate faith, obligatory practices such as prayer and fasting
are necessary. Islam recognizes that it is important to start with ritual
action. If one’s faith becomes deep through the obligatory practices, onewill continue to do the same practices but without feeling coercion.
The Qur’an says that as God, the creator of human beings, knows bestwhat they can do and what they cannot, He never orders to do what theycannot. Although fasting seems very hard and almost impossible from aJapanese perspective, the Qur’an states that it is within human reach. It
is also written that Islamic asceticism is more simplified than the Jewish
ones.

6. The Five Religious Duties (The Five Pillars)
Islam imposes all believers on five religious duties known as the Five
Pillars, and they are well incorporated into everyday life. Prayer (Salat)
is performed five times a day, and fasting (Sawm) is done during amonth Ramadan every year. After eating breakfast before sun rise one
must keep fasting till sunset during a whole month. Whereas strict
observers do not even drink water, children, the sick, the pregnant andlactating mothers do not need fasting. As soon as the sun sets, such signals as fluorescent lights on minarets of Mosques, or drumming, tell theend of fasting of the daytime, and people enjoy Iftaar meal with family
and friends. Thirdly, the pilgrimage to Mecca (Hajj) in the month of pil-THE BASIC TEACHINGS OF ISLAM

grimage is a duty once through a lifetime. The pilgrimage to Mecca atother seasons is not regarded as Hajj, but called Umrah (lesser pilgrimage). Those who have completed Hajj are highly respected by neighbors. The number of pilgrims is assigned the quota to major Muslim
countries every year, and they are chosen from each municipality or
region. There are certain programs for Hajj in Islamic world: chosenmembers have to take lessons about manners and etiquette of Hajj,
using Video tapes today, at certain places in their country before departure, and some religious leaders are delegated as guide by each country.
Zakat is stipulated alms, whose amount is to some degree decided byincome, whereas Sadaqa is a free charity. Both have greatly contributed
to social welfare and public service in Islamic society, and still effective
today. According to a Turkish student, his father, a farmer, donates agoat as Zakat to poor neighbors every year. Waqf is a kind of alms, usually the property endowment by means of will after death. As its original meaning is to stop the ownership of property, namely to ascribe it toGod, it belongs to nobody, and used for various purposes. When man
designates his properties such as land, orchard, and buildings as waqf,
he decides the purpose and usage, for example, to found a school,
library, orphanage, mosque and other facilities, and also appoints a manager. Many public facilities in the Islamic world have been maintainedby waqf. It should be stressed that Islam has operated such social cooperative systems as waqf from the beginning till today.
Finally, the Profession of Faith, Shahadah, means to recite “There isno god but Allah, and Muhammad is his messenger” in Arabic. If one
wishes to convert to Islam, it is enough for one to recite it in Arabic
before a religious leader (Imam) at any mosque. These Five Pillars are
the religious duties of all Muslims. The detailed methods of these practices, and also alternative duties when one could not carry out them, are
set out in the Shari’ah.
Asides from the ritual precepts mentioned above, the Shari’ah comprehends a variety of social norms. Although the idea of Shari’ah isquite different from modern state law, it includes several legal rules,
mainly regarding family law and commercial law. Additionally, it also
includes moral standards, manners, dietary laws forbidding the eating of
pork, and so on. In theory, the Shari’ah is concerned with all kinds ofMuslim acts, both the ritual and the other social acts, and all acts are
divided into five categories. The five categories are: obligatory (breachesof which are punishable), meritorious (the fulfillment of which is desirable, but breaches are not punishable), reprehensible (the avoidance of
which is desirable, although the perpetration is not punishable), forbid-

90

THE BASIC TEACHINGS OF ISLAM

den (the perpetration of which is punishable) and, lastly, neutral (doingor not doing of which is permissible). The final category cannot becalled a prescript in a usual sense. The majority of acts belong to thiscategory. In a word, any kind of Muslim’ acts is covered by the
Shari’ah. Generally speaking, obligatory and forbidden acts correspondto law, while meritorious and reprehensible acts are moralistic. However, these categories are also applicable to ritual acts and manners. For
example, it is laid down in the Shari’ah that such and such a way ofpraying is desirable but not obligatory, or that other manner of prayer isforbidden. To reiterate, all aspects of human lifestyle are governed by asingle system of the Shari’ah in Islam.
Although Islam definitely denied the religion of Jahiliyyah, it adopted
a number of customs, customary laws of the Jahiliyyah period into the
Shari’ah. As a reason for this, when a new religion is founded in history,
it cannot utterly destroy the previous society and culture to replace itwith the new ideal ones. Since Islam as a new religion was establishedin Arab tribal society at seventh century, it could not but keep somehow
continuity with the Jahiliyyah society. As well as Christianity and Buddhism, Islam has the universal ideas, but they can not be completely
realized at once in the newly founded Ummah. Even the Qur’anic precepts reflect, to some extent, customs of Jahiliyyah. Marriage with as
many as four wives is allowed in the Qur’an. A man could marry many
wives during the Jahiliyyah period, but Islam limited the number ofwives to four. There seemed to be another sociological reason. When
Muslims fought with disbelievers at the very beginning, many men died,leaving behind their families. To support them, the Qur’an allows
wealthy men to get lawfully married with widows, which can be considered as a policy of welfare for the widows. According to the Qur’an,
however, a man has to treat his wives equally in all respects, both financially and spiritually. Therefore, as most male Muslims say today that awife is more than enough, the monogamy has been popular among ordinary Muslims.

7. The Formulation of Shari’ah and Politics
It took over 100 years after Muhammad’s death that the Shari’ah was
systematized. Although the process of its formation shows some Islamic
features, I do not have time to explain it in detail here. I will briefly
explain some of the important characteristic. The Qur’an is the primarysource of precepts in Shari’ah. But as it is not a legal code, the precepts
in the Qur’an are far from sufficient to maintain the social order. While

THE BASIC TEACHINGS OF ISLAM

91

the Prophet lived, revelations continued. Concerning troubles which
believers asked or consulted him, sometimes revelations were given,
otherwise he himself could judge. The words and practices of theProphet (Sunnah) became exemplar after the Qur’an. It is highly probable that he allowed Muslims to follow some of previous customs of the
Jahiliyyah period. The Prophet’s Sunnahs were recorded apart from the
Qur’an after his death in a unique literary form called hadith. The collection of hadiths is called also Hadith (The Tradition), which is the second Holy Scripture. Each hadith consists of two parts; the main part(matn) is the record of the sunnahs of the Prophet, and the other part isthe genealogy of transmitters (isnad) who collected the sunnahs fromolder generations. As Islam never founded an institution of church, thegenealogy of transmitters implies the testimony of the Ummah, andplays the function of authorizing the record’s authenticity. If it had had achurch, it would compile the authorized edition of Hadith. There are
numerous editions of Hadith among Sunni Muslims, and Shiite Muslims
independently compiled Hadith.
Though the Caliphate began after the Prophet’s death, the Shari’ah
was not issued by the caliphs, the successors of the Prophet, for they
were political and military leaders but never monopolized all the power.
Instead, his close companions solved troubles in various regions of the
Ummah. Just as Muhammad was not a jurist, they were not jurists, andtheir judgments were lack of legal skill and seemed arbitrary without
any reference to the Qur’anic text. However, because their judgments
would be firmly based on the spirit of Islam, they were trusted. As wellas the judgments of the Prophet which became Sunnahs, those of his
companions were used afterwards as precedents. As time went by, born
Muslims increased, which means that Islam became a firmly establishedreligion, but also that their faith would become lax. Then, the judgmental criteria of arbitrary judgments would become less trustworthy, andinstead of them, the judgments based on the text of the Qur’an andHadith became more popular. To add one more feature, it is speculated
that such judgments in early period adopted many local customary rulesof the Jahiliyyah period.
As jurists gradually grew, methodologies of legal judgments became
elaborated. Local jurists continued to solve troubles based on the Qur’anand Sunnahs. When no rule was found in the two, they used ijma’ (consensus) in respective regions, and also qiyas (analogical inference) inorder to find and validate a new law. Once consensus was reached abouta precept among local jurists, this would become valid as a law. Regional difference of laws might be brought forth, because legal issues dif-

92

THE BASIC TEACHINGS OF ISLAM

fered from region to region; for example, the right and rules of irrigation
were crucial in Iraq where the Tigris and Euphrates rivers flow, but outof concern in Mecca or Medina where no source of water was. In thisway, regional schools of law were naturally formulated.
In the Abbasid dynasty, the regional differences in the judicial systemwere considered inconvenient and attempts to unify them began. What
was unified was the priority of the four sources of law; the Qur’an,
Sunnah and ijma’ and qiyas. In fact, the systematization of Shari’ahmeant not an issue of legal code, but the confirmation of the four
sources of law. While the Qur’an and Sunnah are the material sources oflaws, ijma’ and qiyas are the methodologies of law findings, which had
been used by local groups of jurists. Though ijma’ seemed to mean theconsensus of the Ummah, and has been one of the four sources of law,
Islam has never held any council or institution for ijma’. Certainly thismay seem odd, but the idea of ijma’ may symbolize the authority of the
Ummah. The qiyas is an analogical method of deriving a new rule basedon text of the Qur’an and Sunnahs. If no precept was found among thefirst three sources, a jurist could use it. In other word, jurists’ discretion
was quite limited. These were the formative process of the Shari’ah. It
must be understood that the systematization of the Shari’ah was notenacted by issue of the Shari’ah code at a point of time in history, as
done in modern state laws, but rather gradually formulated since thelifetime of the Prophet. After the systematization, there still remained
different groups of jurists, which resulted in the formation of four orthodox schools of jurisprudence in Sunni Islam.
Though briefly, I would like to explain the idea of politics in Islam. In
a word, Islamic politics is basically the rule base on the Shari’ah. The
Ummah is the sphere in which the Shari’ah is applied. In the Middle
East, where the vast majority of people are Muslims, whole regions,more strictly speaking, each of the modern states, belong to the Ummah.
In regions like Japan where Muslims remain minority, the Shari’ah isapplied to individual Muslims, because each Muslim is a member of the
Ummah.
Immediately after the death of the Prophet, though the Shari’ah was
not systematized, the caliphs began to rule the Ummah. After caliphs
lost their power, sultans or shahs of Iran became political rulers ofrespective states. As long as their reign was based on Shari’ah, they
were regarded as legitimate rulers of a part of the Ummah. The rule by
the Shari’ah was enabled by the cooperation of political rulers andjurists. The caliph or any political rulers had to obey the Shari’ah, andhad no authority to revise or interpret it. Although the jurists could inter-THE BASIC TEACHINGS OF ISLAM

93

pret and even revise the Shari’ah, they had no real political power andhad to conform to the contemporary political system. It is not appropriate to consider the jurists as the religious authority, and caliphs as thesecular power, for the Shari’ah, different from modern state law,
includes both ritual and social precepts. Even when the Shari’ah was
finally systematized, it did not cover all the cases. In such cases, caliphs
or sultans enacted laws or ordinances unrelated to the Shari’ah, ofwhich the Qanun legal code in the Ottoman Empire is a famous example.
Today the modern Islamic world is divided into numerous states, andmost of them have adopted a Western system of law. Though the
Shari’ah has not been effective in modern political, economic and social
cases, it has still been effective to the full extent in a part of ritual precepts such as prayer and fasting, and also to some extent, in that of family law.

8. Islam and Modernization
Finally, I would like to briefly talk about Islam and modernization. Partsof the Middle East were gradually colonized by the great powers ofEurope. Muslims somehow tried to adopt this modern Western science,technology and system of education. That was the beginning of modernization, which was similar to Japanese modernization.
The Ottoman Empire had started accommodating some modern Western systems earlier than the other parts of Islamic world. However, sinceIslam is a religion highly integrated with the society, early Islamic Modernists considered it necessary to reform and modernize Islamic systems, especially the Shari’ah, at the same time as introducing Western
systems. This is an obvious difference from the Japanese modernization.
Though it was an ideal goal that Modernization would be achieved
along the twin-tracks of Westernization and Islamic reformation, thesimultaneous advancement of these two aims was found difficult soon.
Then, the Islamic modernization divided into two lines, the Westernization and the Islamic reform. Islam labeled the former as secularism, andthe latter as revivalism.
Japan rapidly adopted Western systems and succeeded in the modernization, partly because neither Shinto nor Buddhism was strongly
opposed to it. For the reason mentioned above, however, some Muslims
were anxious that religion and state would have to be separated, if theWestern systems were introduced. If so, Islam would cease to be Islam.
Their anxiety seems reasonable, for such integration would be the basis

94

THE BASIC TEACHINGS OF ISLAM

of Islam. However, most Islamic states began to advance Westernization, while harsh opposition to secular modernization occurred fromsome groups of Modernists. The way the latter has chosen is what istoday known as fundamentalism, which is called revivalism by them. It
is called so, because their ideal is not Westernization, but the Islamic
modernization based on the Qur’an and Sunnah.
Fundamentalists wish to establish a modern Islamic society based of
the Qur’an. They do want to modernize their society and also to achieve
economic growth. Nevertheless, their trials seemingly have remained
unsuccessful, for their understanding of the Qur’an tends to rely on literal interpretation of the Qur’an which reflects historical situations of Arabian society in the seventh century, such as discrimination against
women. Thus, their policies actually seem anti-modernist, as found in
Iran Islamic Republic and also in the Taliban, though Fundamentalists
have tried to found an Islamic modern society in a true sense. Logicallyspeaking, it would not be impossible to interpret the Qur’an more rationally and freely, and radical modern interpretations may meet their original aim. But it would be safer for them to be faithful to the letters of the
Qur’an.
Although Islamic opposition to the separation of religion and state
may seem unbelievable and anachronistic from Japanese and Western
perspectives, the basic Islamic view of humanity is certainly coherent
and reasonable. Probably there seems to remain a room for examining if
the western standard is universally valid or not.
No doubt, Muslims have a sense of pride that they were once moreadvanced area than Europe. For Muslims, Christianity is the same
monotheism, sharing the same revelation from the same God, and in
addition, the Qur’an itself is, in today’s jargon, the latest update among
the revelations. Therefore, Muslims do not want to ask Christians aboutmodernization. They think that even democracy would probably beachievable if the Qur’an is interpreted afresh. This is also an underlying
factor which supports revivalism.
Let us mention a little about the anti-American feeling among Muslims. The anti-American stance of fundamentalists is not a simple clashof religions, but rather mainly an issue of economics, and antipathy
towards contemporary international politics led by the West. The countries of the Middle East, other than those which produce oil, are still
impoverished. Although their establishments have followed the Western
initiatives and received various kinds of financial aids, the economic
inequality has not been solved. The fundamentalists actually have been
carrying out medical aids and supported the poor in Egypt and otherTHE BASIC TEACHINGS OF ISLAM

95

places. Even though most Muslims criticize terrorism which killed many
innocent lives, it seems to be a fact that their hidden emotional anger
might be released through terrorism.
Although I do not agree with Muslims’ terrorism either, I do not agreewith American and Israeli militant reactions towards it without serious
efforts to resolve the economic inequity and the Palestinian issue. Long
ago when Islam was dominant in the world, it was comparatively tolerant to both Christianity and Judaism. In any era, the stronger and thewealthier should tolerate the weak, and hence, in the present situation,
the West should more tolerate Muslims.
Both Japan and the Islamic world belonged to different traditions
from that of Europe before modernization. Islam seems to have taken
time to discuss on ways of modernization at the gateway to modernization, and as a result the pace of modernization has been delayed. By
contrast, Japan advanced and completed Westernization without any
serious discussion on its future discrepancies, and today, more than ahundred years later, many Japanese customs and ideas have remained
which clearly differ from the West. Generally speaking, an indigenous
culture with highly developed tradition will not easily lose it, even if it ismodernized and westernized. Probably, if the Islamic world had rapidly
advanced Westernization, Islamic traditions would no doubt have survived. If we examine the process and manners of Japanese modernization in comparison with the Islamic ones, we will discover somefeatures of Japanese culture and religions which are hardly found out bycomparison with the Western culture and religion. In this sense, thestudy of Islam is important.
