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 Most of them We found not men (true) to their covenant: but most of them We found rebellious and disobedient. 102 After them We sent Moses with Our signs to Pharaoh and his chiefs. But they willfully rejected them. Consider the end of the evil-doers. 103 Moses told the Pharaoh, "I am a Messengers from the Lord of the Universe. 104 [Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel." 105 Said he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 Thereupon Moses threw his rod, and suddenly it was a veritable serpent. 107 Then he drew out his hand and it was luminous to the onlookers. 108
