Allah (Arab, al, the, and Illah, God), the Mohammedan name of the Supreme Being. The unity of the Deity is the great postulate of the Mohammedan creed. His attributes are thus summed up by the Koran: "There is no God but God. This only true, great, and most high God has his being through himself; is everlasting; is not begotten and begetteth not; is all-sufficient in himself; fills the universe with his infinity; is the centre in which all things unite, as well the hidden as the manifest; is Lord of the world of bodies and spirits, creator and ruler, almighty, all-wise, all-loving, merciful; and his decrees are unchangeable." Mohammedans repeat a rosary of the 99 epithets of the Supreme Being, closing it with the great, all-including name of Allah. Allah ah-bar (God is great) is a battle cry of the Moslem, while Bism-Illah or Bism-Allah (in the name of God) is the grace before meat of the pious and the invocation at the commencement of every literary performance.
