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 Those cities - We relate to you, [O Muhammad], some of their news. And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers. 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, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 Moses said, "Pharaoh, I am a messenger from the Lord of the Universe, 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 Said he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 Then he drew out his hand, and it appeared luminous to all beholders. 108
