And We set seals upon their hearts so they do not hear. 100 These towns-- We relate to you some of their stories, and certainly their apostles came to them with clear arguments, but they would not believe in what they rejected at first; thus does Allah set a seal over the hearts of the unbelievers 101 And We did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient. 102 After those We sent forth Moses with Our signs to Pharaoh and his nobles, but they dealt with Our signs unjustly. Observe, then, what happened to the mischief-makers. 103 Moses said: "O Pharaoh, I have been sent by the Lord of all the worlds; 104 "Proper it is for me that I say nothing concerning Allah but the truth. Indeed I have come unto you from your Lord with a clear proof. So let the Children of Israel depart along with me." 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 Then [Musa (Moses)] threw his stick and behold! it was a serpent, manifest! 107 Then he drew out his hand, and it appeared luminous to all beholders. 108
