Is it not a lesson for the successors of the past generations that had We wanted, We could have punished them for their sins, sealed their hearts and deprived them of hearing? 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 AND AFTER those [early people] We sent Moses with Our messages unto Pharaoh and his great ones, and they wilfully rejected them: and behold what happened in the end to those spreaders of corruption! 103 Moses said, 'Pharaoh, I am a Messenger from the Lord of all Being, 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 thou comest with a token, then produce it, if thou art of those who speak the truth. 106 Then Moses threw down his staff and suddenly, unmistakably, it appeared as a serpent, 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
