But We seal over their hearts so they do not hear. 100 Those villages We narrate their news to you. Their Messengers came to them with clear proofs, yet they would not believe what they had belied before; as such Allah seals the hearts of the unbelievers. 101 And We found no covenant in most of them; and most of them We found ungodly. 102 After those We sent forth Moses with Our signs to Pharaoh and his assembly, but with it they harmed. Look at the end of the corrupters. 103 Moses said: "O Pharaoh, I have been sent by the Lord of all the worlds; 104 (I am) worthy of not saying anything about Allah except the truth: I have come to you indeed with clear proof from your Lord, therefore send with me the children of Israel 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
