Do not the people who inherited the earth from the (earlier) inhabitants perceive that We could afflict them too for their sins if We pleased, and put seals on their hearts that they may not hear (the voice of truth)? 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 We found most of them untrue to their covenants, indeed We found most of them to be defiant. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 And Musa (Moses) said: "O Fir'aun (Pharaoh)! I am a Messenger from the Lord of the 'Alamin (mankind, jinns and all that exists). 104 "I am duty bound to speak nothing of God but the truth I have brought from your Lord a clear sign; so let the people of Israel depart with me." 105 (Pharaoh) said: If thou comest with a token, then produce it, if thou art of those who speak the truth. 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew forth his hand, and lo! it was white to the beholders. 108
