Among the evidence of Ahl al-Sunnah is: The ayah/verse (interpretation of the meaning): “… but the shayateen (devils) disbelieved, teaching men magic and such things that came down at Babylon to the two angels, Harut and Marut, but neither of these two (angels) taught anyone (such things) till they had said, “We are for trial, so disbelieve not (by learning this magic from us).” And from these (angels) people learn that by which they cause separation between man and his wife, but they could not thus harm anyone except by Allah’s leave. And they learn that which harms them and profits them not.” [2:102] This ayah clearly indicates what is being asked about here, which is that witchcraft is real and that the practitioner of witchcraft can cause separation between a man and his wife and that he can cause harm to people by his witchcraft – if that is decreed by the universal will of Allah.
