To those who inherit the earth in succession to its (previous) possessors, is it not a guiding, (lesson) that, if We so willed, We could punish them (too) for their sins, and seal up their hearts so that they could 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 raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers. 103 Moses said: "O Pharaoh, I have been sent by the Lord of all 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 [Fir'aun (Pharaoh)] said: "If you have come with a sign, show it forth, - if you are one of those who tell the truth." 106 Thereupon Moses threw his rod, and suddenly it was a veritable serpent. 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
