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 And most of them We found not (true) to their covenant, but most of them We found indeed Fasiqun (rebellious, disobedient to Allah). 102 Then we raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers. 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 worthy to say nothing regarding God except the truth. I have brought a clear sign to you from your Lord; so send forth with me the Children of Israel.' 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 Then [Musa (Moses)] threw his stick and behold! it was a serpent, manifest! 107 And he drew forth his hand, and lo, it was white to the beholders. 108
