Is it not a guidance to those who inherit the earth after those who inhabited it that, did We will, We would smite them because of their sins, sealing their hearts so they do not hear? 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 We found no covenant in most of them; and most of them We found ungodly. 102 So We sent Moses with miracles after (these apostles) to the Pharaoh and his nobles, but they behaved with them high-handedly. See then the end of the authors of evil. 103 Moses said: "O Pharaoh! I am a messenger from the Lord of the worlds,- 104 "I am duty bound to speak nothing of God but the truth I have brought from your Lord a clear sign; so let the people of Israel depart with me." 105 (Pharaoh) said: If thou comest with a token, then produce it, if thou art of those who speak the truth. 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 And he drew out his hand, and behold! it was white to all beholders! 108
