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 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 Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 104 And it behoves me to say nothing about Allah except what is true. I have come to you with a clear sign of having been sent from your Lord. So let the Children of Israel go with me.' 105 He said: "If you have brought a sign then display it, if what you say is true." 106 Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)! 107 And he drew forth his hand, and lo, it was white to the beholders. 108
