In Islam, God is seen as the creator and sustainer of the universe, who lives eternally and will eventually resurrect all humans. God is conceived as a perfect, singular, immortal, omnipotent, and omniscient god, completely infinite in all of his attributes. Islam further emphasizes that God is most merciful. The Islamic concept of God is variously described as monotheistic, panentheistic, and monistic.

Omniscience is the capacity to know everything. In Hinduism, Sikhism and the Abrahamic religions, this is an attribute of God. In Jainism, omniscience is an attribute that any individual can eventually attain. In Buddhism, there are differing beliefs about omniscience among different schools.
