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 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 Moses said: O Pharaoh! Lo! I am a messenger from the Lord of 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 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
