Has it not become clear to those who inherited the earth after its [previous] people that if We willed, We could afflict them for their sins? But We seal over their hearts so they do not hear. 100 Those were the towns whose story We relate unto you (O Muhammad SAW). And there came indeed to them their Messengers with clear proofs, but they were not such as to believe in that which they had rejected before. Thus Allah does seal up the hearts of the disbelievers (from each and every kind of religious guidance). 101 Most of them We found not men (true) to their covenant: but most of them We found rebellious and disobedient. 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, 'Pharaoh, I am a Messenger from the Lord of all Being, 104 And it behoves me to say nothing about Allah except what is true. I have come to you with a clear sign of having been sent from your Lord. So let the Children of Israel go with me.' 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 Then he flung down his staff and lo! it was a serpent manifest; 107 And he drew out his hand, and behold! it was white to all beholders! 108
