And they followed [instead] what the devils had recited during the reign of Solomon. It was not Solomon who disbelieved, but the devils disbelieved, teaching people magic and that which was revealed to the two angels at Babylon, Hārūt and Mārūt. But they [i.e., the two angels] do not teach anyone unless they say, "We are a trial, so do not disbelieve [by practicing magic]."1 And [yet] they learn from them that by which they cause separation between a man and his wife. But they do not harm anyone through it except by permission of Allāh. And they [i.e., people] learn what harms them and does not benefit them. But they [i.e., the Children of Israel] certainly knew that whoever purchased it [i.e., magic] would not have in the Hereafter any share. And wretched is that for which they sold themselves, if they only knew. — Saheeh International

2:102 ...followed what the evil ones gave out (falsely) against the power of Solomon: the blasphemers Were,.. teaching men Magic, and such things as came down at babylon to the angels Harut and Marut. But neither of these taught anyone (Such things) without saying: "We are only for trial; so do not blaspheme." They learned from them the means to sow discord between man and wife. But they could not thus harm anyone except by Allah's permission. And they learned what harmed them, not what profited them. And they knew that the buyers of (magic) would have no share in the happiness of the Hereafter. And vile was the price for which they did sell their souls,.. — English Translation (Yusuf Ali)
