Is it not clear to those who inherit the earth in succession from its (previous) possessors, that had We willed, We would have punished them for their sins. And We seal up their hearts so that they hear not? 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 And Moses said: "O Pharaoh! Verily, I am an apostle from the Sustainer of all the worlds, 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 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 Then he flung down his staff and lo! it was a serpent manifest; 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
