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 We have told you the stories of those towns: their messengers came to them with clear signs, but they were never going to believe in something they had already rejected. Thus God seals up the hearts of those who deny the truth. 101 We found no covenant in the most part of them; indeed, We found the most part of them ungodly. 102 Then, after them, We sent Moses with our tokens unto Pharaoh and his chiefs, but they repelled them. Now, see the nature of the consequence for the corrupters! 103 Moses said: 'Pharaoh, I am a Messenger from the Lord of the Worlds, 104 so constituted that I cannot say anything about God but the truth. I have now come unto you with a clear evidence from your Sustainer: let, then, the children of Israel go with me!" 105 He said: "If you have brought a sign then display it, if what you say is true." 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
