Is it not clear to those who inherit the earth in succession from its (previous) possessors, that had We willed, We would have punished them for their sins. And We seal up their hearts so that they hear not? 100 Such were the towns whose story We (thus) relate unto thee: There came indeed to them their messengers with clear (signs): But they would not believe what they had rejected before. Thus doth Allah seal up the hearts of those who reject faith. 101 We found no (loyalty to any) covenant in most of them. Nay, most of them We found wrong-doers. 102 After those We sent forth Moses with Our signs to Pharaoh and his assembly, but with it they harmed. Look at the end of the corrupters. 103 Moses said: O Pharaoh! Lo! I am a messenger from the Lord of the Worlds, 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 He said: "If you have brought a sign then display it, if what you say is true." 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew out his hand, and behold! it was white (with radiance) for the beholders. 108
