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 We did not find the covenant upheld by the majority of them, but We found most of them evildoers. 102 Then We sent after them Moses with Our signs to Pharaoh and his establishment, but they were unjust toward them. So see how was the end of the corrupters. 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 [Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel." 105 [Pharaoh] said, "If you come with a sign, then produce it, if you are telling the truth." 106 Then Moses threw down his staff and suddenly, unmistakably, it appeared as a serpent, 107 And he drew out his hand, and behold! it was white to all beholders! 108
