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 cities - We relate to you, [O Muhammad], some of their news. 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 many among them keeping their promises. However, We did find many evil-doers among them. 102 After the time of those people, We sent Moses with Our miracles to Pharaoh and his people, but they too rejected Our miracles. Consider, how terrible the end of the evil-doers is! 103 Moses told the Pharaoh, "I am a Messengers from the Lord of the Universe. 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 He threw down his staff, and it was clearly a serpent. 107 And he drew out his hand; thereupon it was white [with radiance] for the observers. 108
