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 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 And most of them We found not (true) to their covenant, but most of them We found indeed Fasiqun (rebellious, disobedient to Allah). 102 Then We sent, after them, Moses with Our signs to Pharaoh and his Council, but they did them wrong; so behold thou, how was the end of the workers of corruption! 103 Moses said, "Pharaoh, I am a messenger from the Lord of the Universe, 104 Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me. 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)! 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
