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 These are the dwellings – the affairs of which We relate to you (Prophet Mohammed – peace and blessings be upon him); and indeed their (respective) Noble Messengers came to them with clear proofs; so they were not able to believe in what they had denied before; this is how Allah sets seals upon the hearts of disbelievers. 101 We found most of them untrue to their covenants, indeed We found most of them to be defiant. 102 Then We sent, after them, Moses with Our signs to Pharaoh and his Council, but they did them wrong; so behold thou, how was the end of the workers of corruption! 103 Moses said: 'Pharaoh, 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 thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 Thereupon Moses threw his rod, and suddenly it was a veritable serpent. 107 And he drew out his hand; thereupon it was white [with radiance] for the observers. 108
