Allah

Allah () is the common name for God in the Arabic language. It is similar to Eloah, the name for God in the Hebrew language, and Elaha, the name for God in the Aramaic language.
Muslims commonly use the word Allah for God. Sometimes, people who speak Arabic still use the word Allah when they speak English. In Islam, Allah is Merciful and Allah is the one who loves his followers.
The word Allah is also used with other human feelings that describe God, such as sabur (very patient), halim (does not get angry quickly), or wedud (loving).
In Arabic
Where the word comes from
Around 2000 BC (4000 years ago) there was a group of people called the Canaanites, who lived in the Middle East. They had many gods, and the ruling god was called "El" or "Il." El had power and ruled over everything, and he lived forever. He made the earth and everything else. Later, the word "El" became Eloh or Elaha in the Aramaic language. Another language, Hebrew, changed the Aramaic word to Eloah. In the New Testament (the second book in the Christian Bible), the words "Eli" and "Elohi" were used to mean god. "El" is also in some people's names: Gabri-el, Mika-el, Azrael, Israel, Israel, Yishmael, Emanuel etc.
As a common noun
In Arabic, the general word for a god is ilaah. It can mean a specific god, or any god at all, depending on how it is used.
As a proper noun
As a proper noun, "Allah" is a name for one God. In Arabic, the word al is an article (a word for "the"), so al-ILaah means "The God".
Usually, the word "Allah" is used by Muslims. However, Arab Christians also call their God "Allah."
The name "Allah" is made of four letters in Arabic, (or Alif Lam Lam Ha, from right to left, A-L-L-H, 2111), which when brought together make llh
We can't find a word with a letter pronounced as "lla" by putting two lam together in Arabic.
It may be Al Yah, which means The Yah.
Yah is the God of Banu Hashem/Son of Shem.
Alif Lam Yah ha.
If we write the above letters together it will resemble the calligraphy of the word nowadays pronounced as Allah.
lyh and llh seems to be the same.
In Islam
In Islam, God is usually called "Allah." There are many different names for God in Islam. However, "Allah" is the most common. It means the same thing as any of the other names.
For Muslims, "Allah" describes a single God who is all-powerful and never makes mistakes. Muslims believe that Allah created everything, including the heavens and the Earth, simply by saying Kun Faya Kun ("Be and it is"). Muslims often repeat the word "Allah" many times when they are praying.
In Judaism
In Judaism, God is usually called YHWH (by scholarly convention pronounced Yahweh) and Eloah. Both names are mentioned in the Old Testament and are one of the seven names of God in Judaism. It can also be noted that in Judaism, Elohim is a name for God and in Islam, Allahuma is a name for God. Since Jewish and Muslim names of God are very similar, Jews and Muslims say that they believe in the same God.
In Christianity
Arab Christians call their God "Allah" due to Arabic language. In the Arabic translation of the Christian Bible, God is referred to by "Allah". The word "Allah" was also used in the old Turkish translations of the Bible, e.g. 1941 version, due to Islamic culture being common in Turkey, and because the Turkish language was influenced by the Arabic Language.
