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 so constituted that I cannot say anything about God but the truth. I have now come unto you with a clear evidence from your Sustainer: let, then, the children of Israel go with me!" 105 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
