Has it not become clear to those who inherited the earth after its [previous] people that if We willed, We could afflict them for their sins? But We seal over their hearts so they do not hear. 100 Those cities - We relate to you, [O Muhammad], some of their news. And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers. 101 Most of them We found not men (true) to their covenant: but most of them We found rebellious and disobedient. 102 After them We sent Moses with Our signs to Pharaoh and his chiefs. But they willfully rejected them. Consider the end of the evil-doers. 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 104 duty-bound to say nothing about God but the truth, and I have brought you a clear sign from your Lord. Let the Children of Israel go with me." 105 (Pharaoh) said: If thou comest with a token, then produce it, if thou art of those who speak the truth. 106 So he threw his rod, then lo! it was a clear serpent. 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
