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 no (loyalty to any) covenant in most of them. Nay, most of them We found wrong-doers. 102 Then We sent after them Moses with Our signs to Pharaoh and his establishment, but they were unjust toward them. So see how was the end of the corrupters. 103 And Moses said: "O Pharaoh! Verily, I am an apostle from the Sustainer of all the worlds, 104 incumbent upon me is that I say nothing of Allah except the truth. I bring you a clear proof from your Lord. So let the Children of Israel depart with me' 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
