There is a group of the Jews who listen to lies and listen to a people who have never met you. They twist the meaning of words. They say, "If this is given to you, take it, and if not, beware."If Allah wishes to mislead anyone, no one can help him against Allah. Those are they whose hearts Allah does not wish to purify. For them is humiliation in this world and a great torment in the Hereafter."
