Allah (Arabic: الله‎Allāh, IPA: [ʔalˤːɑːh]  ( listen)) is a word for God used in the context of Islam. In Arabic, it is the standard word for "God," used not only by Muslims, but also by Bahá'ís, Eastern Catholic Christians, Eastern Orthodox Christians, and Mizrahi Jews.
The term Allāh is derived from a contraction of the Arabic definite article al- "the" and ʼilāh "deity, god" to al-lāh meaning "the [sole] deity, God" (ho theos monos).[4] Cognates of the name "Allāh" exist in other Semitic languages, including Hebrew and Aramaic.[5] Biblical Hebrew mostly uses the plural form (but functional singular) Elohim. The corresponding Aramaic form is ʼĔlāhā ܐܠܗܐ in Biblical Aramaic and ʼAlâhâ ܐܲܠܵܗܵܐ in Syriac.[6]

The name was previously used by pagan Meccans as a reference to the creator deity, possibly the supreme deity in pre-Islamic Arabia.[7][8] The concepts associated with the term Allah (as a deity) differ among religious traditions. In pre-Islamic Arabia amongst pagan Arabs, Allah was not considered the sole divinity, having associates and companions, sons and daughters–a concept which Islam thoroughly and resolutely did away with. In Islam, the name Allah is the supreme and all-comprehensive divine name. All other divine names are believed to refer back to Allah.[9] Allah is unique, the only Deity, creator of the universe and omnipotent.[1][2] Arab Christians today use terms such as Allāh al-ʼAb ( الله الأب, "God the Father") to distinguish their usage from Muslim usage.[10] There are both similarities and differences between the concept of God as portrayed in the Qur'an and the Hebrew Bible.[11] It has also been applied to certain living human beings as personifications of the term and concept.[12][13]

Unicode has a codepoint reserved for Allāh, ﷲ = U+FDF2.[14] Many Arabic type fonts feature special ligatures for Allah.[15]
Pre-Islamic Arabia

In pre-Islamic Arabia, Allah was used by Meccans as a reference to the creator-god, possibly the supreme deity.[16]
Allah was not considered the sole divinity; however, Allah was considered the creator of the world and the giver of rain. The notion of the term may have been vague in the Meccan religion.[4] Allah was associated with companions, whom pre-Islamic Arabs considered as subordinate deities. Meccans held that a kind of kinship existed between Allah and the jinn.[17] Allah was thought to have had sons[18] and that the local deities of al-ʻUzzá, Manāt and al-Lāt were His daughters.[19] The Meccans possibly associated angels with Allah.[20][21] Allah was invoked in times of distress.[21][22] Muhammad's father's name was ‘Abdallāh meaning the “servant of Allāh.” or "the slave of Allāh"[21]
