Is it not clear to those who inherit the earth after its (former) residents that if We please We would afflict them on account of their faults and set a seal on their hearts so they would not hear. 100 To those [earlier] communities - some of whose stories We relate to you - there had indeed come Messengers with clear proofs, but they would not believe what they had once rejected as false. Thus it is that Allah seals the hearts of those who deny the truth. 101 We did not find many among them keeping their promises. However, We did find many evil-doers among them. 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 Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 I must only speak what is true about God. I have brought you miracles from your Lord; therefore, let the children of Israel go free". 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 Then [Musa (Moses)] threw his stick and behold! it was a serpent, manifest! 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
