Allah is a word for God. In Arabic, the word means simply „the God.” It is used mainly by Muslims, Arab Christians, and often, albeit not exclusively, by Bahá’ís, Arabic-speakers, Indonesian, Malaysian and Maltese Christians, Mizrahi Jews and Sikhs.
In pre-Islamic Arabia, Allah was used by Meccans as a reference to the creator-god, possibly the supreme deity. 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. 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. Allah was thought to have had sons and that the local deities of al-ʿUzzā, Manāt and al-Lāt were His daughters. The Meccans possibly associated angels with Allah. Allah was invoked in times of distress. Muhammad’s father’s name was ʿAbd-Allāh meaning „the slave of Allāh”
According to Islamic belief, Allah is the proper name of God, and humble submission to His Will, Divine Ordinances and Commandments is the pivot of the Muslim faith. „He is the only God, creator of the universe, and the judge of humankind.” „He is unique (wāḥid) and inherently one (ʾaḥad), all-merciful and omnipotent.” The Qur’an declares „the reality of Allah, His inaccessible mystery, His various names, and His actions on behalf of His creations.”
Most Muslims append „swt” after mentioning Allah. This is an acronym for the Arabic words: „Subhanahu Wa Ta’ala,” which roughly translated means „The most glorified, the most high.” It is a way for Muslims to glorify Allah when mentioning His name.
In Islamic tradition, there are 99 Names of God (al-ʾasmāʾ al-ḥusnā lit. meaning: „The best names”) each of which evoke a distinct characteristic of Allah. All these names refer to Allah, the supreme and all-comprehensive divine name. Among the 99 names of God, the most famous and most frequent of these names are „the Merciful” (ar-raḥmān) and „the Compassionate” (al-raḥīm).
