God in Islam's theology is omniscient.
In Islamic theology , God ( [ الله , translit = Allah , Allāh ] ) is the all-powerful and all-knowing creator , sustainer , ordainer and judge of everything in existence . Islam emphasizes that God is strictly singular : unique , inherently One , also all-merciful and omnipotent . According to Islamic teachings , beyond the Throne and according to the Quran , `` No vision can grasp him , but His grasp is over all vision : He is above all comprehension , yet is acquainted with all things .
