The Quran, like Gnostic cosmology, makes a sharp distinction between this world and the afterlife. God is commonly thought of as being beyond human comprehension. In some Islamic schools of thought, somehow identifiable with the Gnostic Monad. However, according to Islam and unlike most Gnostic sects, not rejection of this world, but performing "good deeds" leads to the heaven. And according to the Islamic belief in strict Oneness of God, there was no room for a lower deity; such as the demiurge. According to Islam, both "good" and "evil" come from one God, a position especially opposed by the Manichaeans. Ibn al-Muqaffa depicted the Islamic deity as a demonic entity who "fights with humans and boasts about His victories" and "sitting on a throne, from which He can descend". It would be impossible that both light and darkness were created from one source, since they were regarded as two different eternal principles. Muslim theologists countered this accusation by the example of a repeating sinner, who says: "I laid, and I repent"; this would prove that good can also result out of evil.
