Is it not a lesson for the successors of the past generations that had We wanted, We could have punished them for their sins, sealed their hearts and deprived them of hearing? 100 Those villages We narrate their news to you. Their Messengers came to them with clear proofs, yet they would not believe what they had belied before; as such Allah seals the hearts of the unbelievers. 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 the Universe, 104 so constituted that I cannot say anything about God but the truth. I have now come unto you with a clear evidence from your Sustainer: let, then, the children of Israel go with me!" 105 [Pharaoh] said, "If you come with a sign, then produce it, if you are 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 lo! it appeared [shining] white to the beholders. 108
