Has it not, then, become plain to those who have inherited the earth in the wake of the former generations that, had We so willed, We could have afflicted them for their sins, (they, however, are heedless to basic facts and so) We seal their hearts so that they hear nothing. 100 To those [earlier] communities - some of whose stories We relate to you - there had indeed come Messengers with clear proofs, but they would not believe what they had once rejected as false. Thus it is that Allah seals the hearts of those who deny the truth. 101 We did not find many of them faithful to their promises, and found many of them 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: "O Pharaoh! I am a messenger from the Lord of the worlds,- 104 I must only speak what is true about God. I have brought you miracles from your Lord; therefore, let the children of Israel go free". 105 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
