What! do you enjoin men to be good and neglect your own souls while you read the Book; have you then no sense?

And they followed what the Shaitans chanted of sorcery in the reign of Sulaiman, and Sulaiman was not an unbeliever, but the Shaitans disbelieved, they taught men sorcery and that was sent down to the two angels at Babel, Harut and Marut, yet these two taught no man until they had said, "Surely we are only a trial, therefore do not be a disbeliever." Even then men learned from these two, magic by which they might cause a separation between a man and his wife; and they cannot hurt with it any one except with Allah's permission, and they learned what harmed them and did not profit them, and certainly they know that he who bought it should have no share of good in the hereafter and evil was the price for which they sold their souls, had they but known this.

Is he then who has with him clear proof from his Lord, and a witness from Him recites it and before it (is) the Book of Musa, a guide and a mercy? These believe in it; and whoever of the (different) parties disbelieves in it, surely it is the truth from your Lord, but most men do not believe.
