Is it not a guidance to those who inherit the earth after those who inhabited it that, did We will, We would smite them because of their sins, sealing their hearts so they do 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 and in most of them We found no [inner] bond with anything that is right - and most of them We found to be iniquitous indeed. 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 And Musa said: O Firon! surely I am an apostle from the Lord of the worlds: 104 [Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel." 105 (Pharaoh) said: If thou comest with a token, then produce it, if thou art of those who speak the truth. 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew forth his hand, and lo, it was white to the beholders. 108
