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 in most of them We found no [inner] bond with anything that is right - and most of them We found to be iniquitous indeed. 102 Then after them We sent Musa (Moses) with Our Signs to Fir'aun (Pharaoh) and his chiefs, but they wrongfully rejected them. So see how was the end of the Mufsidun (mischief-makers, corrupts, etc.). 103 Moses said: O Pharaoh! Lo! I am a messenger 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 thou comest with a token, then produce it, if thou art of those who speak the truth. 106 Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)! 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
