Do not the people who inherited the earth from the (earlier) inhabitants perceive that We could afflict them too for their sins if We pleased, and put seals on their hearts that they may not hear (the voice of truth)? 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 found most of them not true to their words; and indeed We found most of them disobedient. 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 "I am duty bound to speak nothing of God but the truth I have brought from your Lord a clear sign; so let the people 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 Then he flung down his staff and lo! it was a serpent manifest; 107 And he drew forth his hand, and lo, it was white to the beholders. 108
