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 towns-- We relate to you some of their stories, and certainly their apostles came to them with clear arguments, but they would not believe in what they rejected at first; thus does Allah set a seal over the hearts of the unbelievers 101 Most of them We found not men (true) to their covenant: but most of them We found rebellious and disobedient. 102 After those We sent forth Moses with Our signs to Pharaoh and his nobles, but they dealt with Our signs unjustly. Observe, then, what happened to the mischief-makers. 103 Moses said, 'Pharaoh, I am a Messenger from the Lord of all Being, 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 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 Thereupon Moses threw his rod, and suddenly it was a veritable serpent. 107 And he drew forth his hand, and lo, it was white to the beholders. 108
