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 Unto those [earlier] communities - some of whose stories We [now] relate unto thee - there had indeed come apostles of their own with all evidence of the truth; but they would not believe in anything to which they had once given the lie: thus it is that God seals the hearts of those who deny the truth; 101 And We did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient. 102 Then We sent, after them, Moses with Our signs to Pharaoh and his Council, but they did them wrong; so behold thou, how was the end of the workers of corruption! 103 And Musa said: O Fir'awn! 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 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
