Allāh is the standard Arabic word for "God". The term is best known in the West for its use by Muslims as a reference to God...

[1] Arabic-speakers of all faiths, including Christians and Jews, use the word "Allah" to mean "God".

[2] The Muslim and Christian Arabs of today have no other word for 'God' than 'Allah'.

[3] In pre-Islamic Arabia, Allah was used by pagan Meccans as a reference to the creator-god, possibly the supreme deity.

In Islam, Allah is the only deity, transcendent creator of the universe, and the judge of humankind.

[5] Some Islamic scholars believe that the term "Allāh" should not be translated, arguing that "Allāh" as used in Islam is a special and glorified term whose use should be preserved, while God can also be used in reference to deities worshiped by polytheists.

- According to F. E. Peters, "The Qur'an insists, Muslims believe, and historians affirm that Muhammad and his followers worship the same God as the Jews.[Qur'an 29:46] The Quran's Allah is the same Creator God who covenanted with Abraham". Peters states that the Qur'an portrays Allah as both more powerful and more remote than Yahweh, and as a universal deity, unlike Yahweh who closely follows Israelites.

According to the tradition of Islam there are more than 99 Names of God (al-asma al-husna lit. meaning: "The best names") each of which evoke a distinct characteristic of Allah. The most famous and most frequent of these names are "the Merciful" (al-rahman) and "the Compassionate" (al-rahim).
