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 We did not find most of them true to their covenants; indeed We found most of them to be transgressors. 102 After the time of those people, We sent Moses with Our miracles to Pharaoh and his people, but they too rejected Our miracles. Consider, how terrible the end of the evil-doers is! 103 Moses said: "O Pharaoh, I have been sent by the Lord of all 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 come with a sign, then produce it, if you are telling the truth." 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
