And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers. 101 We did not find most of them true to their covenants; indeed We found most of them to be transgressors. 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! Lo! I am a messenger from the Lord of the Worlds, 104 One for whom it is right to say nothing but truth about Allah. Now have I come unto you (people), from your Lord, with a clear (Sign): So let the Children of Israel depart along with me." 105 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)! 107 And he drew out his hand, and behold! it was white to all beholders! 108
