"If a slave in every letter of the Qur'an is given a thousand understanding did not reach the end of which God deposited in one verse of his book. Because it is the speech of God, and his Speech are his adjective. As God has no end, As well no end to understand his speech. But each one understands as much as God gives him the power of knowledge. The speech of God not a creature. So the creature's understandings does not reach the end of his understanding ."
