The Cow - 2:102
"They followed what the devils told them about the authority of Solomon. But Solomon did not disbelieve; it was the devils who taught the people sorcery and what was revealed to the two angels Harut and Marut in Babylon. These two said: "This is a test; do not be ungrateful (by misusing this knowledge)."But they used what they learned from those two to drive a wedge between a husband and his wife. But they could not harm anyone without Allah´s permission. They were learning that which harmed them, not that which benefited them. Moreover, they knew well that those who were its customers had no share in the Hereafter. How bad is that for which they sold their personalities. If only they knew!"
