A--- Sorcery is real and it has an impact in case it coincides with the Universal Divine Decree, as explained by Allah the Almighty: {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}. (Al-Baqarah, 102)

In addition, its effect is affirmed in the Prophetic Hadiths. As for the sorcerer, he is a disbeliever in Allah the Almighty and in what has been revealed to Muhammad (Peace be upon him). Allah the Almighty says:

{...Neither of these two (angels) taught anyone (such things) till they had said: "We are only 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. And indeed they knew that the buyers of it (magic) would have no share in the Hereafter}. (AlBaqarah, 102)
