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.

And were it not for Allah's grace upon you and His mercy a party of them had certainly designed to bring you to perdition and they do not bring (aught) to perdition but their own souls, and they shall not harm you in any way, and Allah has revealed to you the Book and the wisdom, and He has taught you what you did not know, and Allah's grace on you is very great.

O you who believe! take care of your souls; he who errs cannot hurt you when you are on the right way; to Allah is your return, of all (of you), so He will inform you of what you did.

Say: I do not control any benefit or harm for my own soul except as Allah please; and had I known the unseen I would have had much of good and no evil would have touched me; I am nothing but a warner and the giver of good news to a people who believe.
