Has it, then, not become obvious unto those who have inherited the earth in the wake of former generations that, if We so willed, We could smite them [too] by means of their sins, sealing their hearts so that they cannot hear [the truth]? 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 found no covenant in the most part of them; indeed, We found the most part of them ungodly. 102 AND AFTER those [early people] We sent Moses with Our messages unto Pharaoh and his great ones, and they wilfully rejected them: and behold what happened in the end to those spreaders of corruption! 103 And Musa said: O Firon! surely I am an apostle 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 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 Therefore Moosa put down his staff – it immediately turned into a visible python. 107 Then he drew out his hand, and it appeared luminous to all beholders. 108
