Muslims
Muslims (, ) are people who adhere to Islam, an Abrahamic religion. They consider the Quran, the central religious text of Islam, to be the verbatim word of the God of Abraham as it was revealed to Muhammad, the main Islamic prophet and messenger. The majority of Muslims also follow the teachings and practices of Muhammad ("sunnah") as recorded in traditional accounts ("hadith"). Numbering approximately 1.8 billion , Muslims comprise about 24.1% of the world population. By the percentage of the total population in a region considering themselves Muslim: 91% in the Middle East and in North Africa (MENA), 81% in Central  Asia, 65% in the Caucasus, 40% in Southeast Asia, 31% in South Asia, 30% in Sub-Saharan Africa, 25% in Asia and in Oceania collectively, around 6% in Europe, and 1% in the Americas. The two largest Islamic sects are Sunni Islam (75–90%) and Shia Islam (10–20%). About 12% of Muslims live in Indonesia, the largest Muslim-majority country; 100 * 480/1570 round 0% of Muslims live in South Asia, the largest population of Muslims in the world by numbers; 100 * 315/1571 round 0% in the Middle East and North Africa, where it is the dominant religion; and 15% in Sub -Saharan Africa. Muslims are the overwhelming majority in Central Asia, the majority in the Caucasus and widespread in Southeast Asia. India is the country with the largest Muslim population outside Muslim-majority countries. Sizeable Muslim communities are also found in the Americas, China, and throughout Europe. Islam is the fastest-growing major religion in the world. Etymology. The word "muslim" (, ; , , or "moslem" , ) is the active participle of the same verb of which "islām" is a verbal noun, based on the triliteral "S-L-M" "to be whole, intact". A female adherent is a "muslima" () (also transliterated as "Muslimah" ). The plural  form in Arabic is "muslimūn" () or "muslimīn" (), and its feminine equivalent is "muslimāt" (). The ordinary word in English is "Muslim". In the 20th century the preferred spelling in English was "Moslem", but this has now fallen into disuse. The word "Mosalman" (, alternatively "Mussalman") is a common equivalent for "Muslim" used in Central and South Asia. In English it was sometimes spelled Mussulman and has become archaic in usage. Until at least the mid-1960s, many English-language writers used the term "Mohammedans" or "Mahometans". Although such terms were not necessarily intended to be pejorative, Muslims argue that the terms are offensive  because they allegedly imply that Muslims worship Muhammad rather than God. Other obsolete terms include "Muslimite" and "Muslimist". In Medieval Europe, Muslims were commonly called Saracens. The Muslim philosopher Ibn Arabi said: Qualifier. To become a Muslim and to convert to Islam, it is essential to utter the "Shahada", one of the Five Pillars of Islam, a declaration of faith and trust that professes that there is only one God "(Allah)" and that Muhammad is God's messenger. It is a set statement normally recited in Arabic: "ašhadu ʾal-lā ʾilāha ʾillā-llāhu wa ʾašhadu ʾanna muħammadan rasūlu-llāh" () "I  testify that there is no god [worthy of worship] except Allah, and Muhammad is the messenger of Allah." In Sunni Islam, the shahada has two parts: "la ilaha illa'llah" (there is no god but Allah), and "Muhammadun rasul Allah" (Muhammad is the messenger of God), which are sometimes referred to as the first "shahada" and the second "shahada". The first statement of the shahada is also known as the "tahlīl". In Shia Islam, the shahada also has a third part, a phrase concerning Ali, the first Shia Imam and the fourth Rashid caliph of Sunni Islam: (), which translates to "Ali  is the "wali" of God". In Quranist Islam, the shahada is the testimony that there is no god but Allah ("la ilaha illa'llah" ). The religious practices of Muslims are enumerated in the Five Pillars of Islam: the declaration of faith ("shahadah"), daily prayers ("salah"), almsgiving ("zakat"), fasting during the month of Ramadan ("sawm"), and the pilgrimage to Mecca ("hajj") at least once in a lifetime. In Islamic theology. The Qur'an describes many prophets and messengers within Judaism and Christianity, and their respective followers, as Muslim. Some of those that were mentioned are: Adam, Noah, Abraham, Ishmael, Jacob, Moses, and Jesus  and his apostles are all considered to be Muslims in the Qur'an. The Qur'an states that these men were Muslims because they submitted to God, preached His message and upheld His values, which included praying, charity, fasting and pilgrimage. Thus, in Surah 3:52 of the Qur'an, Jesus' disciples tell him, "We believe in God; and you be our witness that we are Muslims ("wa-shahad be anna muslimūn")." In Islamic belief, before the Qur'an, God had given the Tawrat (Torah) to Moses, the Zabur (Psalms) to David and the Injil (Gospel) to Jesus, who are all considered important Muslim prophets . Demographics. The most populous Muslim-majority country is Indonesia, home to 12.7% of the world's Muslims, followed by Pakistan (11.0%), Bangladesh (9.2%), Nigeria (5.3%) and Egypt (4.9%). About 20% of the world's Muslims live in the Middle East and North Africa. Sizable minorities are also found in India, China, Ethiopia, the Americas, Australia and parts of Europe. The country with the highest proportion of self-described Muslims as a proportion of its total population is Morocco. Over 75–90% of Muslims are Sunni. The second and third largest sects, Shia and Ahmadiyya, make up 10–20%, and 1% respectively. With  about 1.8 billion followers (2019), almost a quarter of earth's population, Islam is the second-largest and the fastest-growing religion in the world, primarily due to the young age and high fertility rate of Muslims, with Muslims having a rate of (3.1) compared to the world average of (2.5). According to the same study, religious switching has no impact on Muslim population, since the number of people who embrace Islam and those who leave Islam are roughly equal. A Pew Center study in 2016 found that Muslims have the highest number of adherents under the age of 15  (34% of the total Muslim population) of any major religion, while only 7% are aged 60+ (the smallest percentage of any major religion). According to the same study, Muslims have the highest fertility rates (3.1) of any major religious group. The study also found that Muslims (tied with Hindus) have the lowest average levels of education with an average of 5.6 years of schooling, though both groups have made the largest gains in educational attainment in recent decades among major religions. About 36% of all Muslims have no formal schooling, and Muslims have the lowest average levels of higher  education of any major religious group, with only 8% having graduate and post-graduate degrees. Culture. Muslim culture or Islamic culture are terms used to describe the cultural practices common to Muslims and historically Islamic people. The early forms of Muslim culture, from the Rashidun Caliphate to early Umayyad period, were predominantly Arab, Byzantine, Persian and Levantine. With the rapid expansion of the Islamic empires, Muslim culture has influenced and assimilated much from the Persian, Egyptian, Caucasian, Turkic, Mongol, South Asian, Malay, Somali, Berber, Indonesian, and Moro cultures.
