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 Most of them We found not men (true) to their covenant: but most of them We found rebellious and disobedient. 102 Then after them We sent Musa (Moses) with Our Signs to Fir'aun (Pharaoh) and his chiefs, but they wrongfully rejected them. So see how was the end of the Mufsidun (mischief-makers, corrupts, etc.). 103 Moses said, 'Pharaoh, I am a Messenger from the Lord of all Being, 104 One for whom it is right to say nothing but truth about Allah. Now have I come unto you (people), from your Lord, with a clear (Sign): So let the Children of Israel depart along with me." 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
