And they followed the device which the devils devised against the kingdom of Solomon; and Solomon was not an unbeliever; but the devils believed not, they taught men sorcery, and that which was sent down to the two angels at Babel, Harut and Marut: Yet those two taught no man until they had said, verily we are a temptation, therefore be not an unbeliever. So men learned from those two a charm by which they might cause division between a man and his wife; but they hurt none thereby, unless by God's permission; and they learned that which would hurt them, and not profit them; and yet they knew that he who bought that art should have no part in the life to come, and woful is the price for which they have sold their souls, if they knew it.
