Is it not plain to those who inherit the earth after its inhabitants that if We willed We could smite them for their sins and set a seal upon their hearts, so that they do not hear. 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 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 have been sent by the Lord of all 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 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 And he drew forth his hand (from his bosom), and lo! it was white for the beholders. 108
