Is it not clear to those who inherit the earth after its (former) residents that if We please We would afflict them on account of their faults and set a seal on their hearts so they would not hear. 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 After those We sent forth Moses with Our signs to Pharaoh and his nobles, but they dealt with Our signs unjustly. Observe, then, what happened to the mischief-makers. 103 Moses said: O Pharaoh! Lo! I am a messenger from the Lord of the Worlds, 104 incumbent upon me is that I say nothing of Allah except the truth. I bring you a clear proof from your Lord. So let the Children of Israel depart with me' 105 Said he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 And he drew forth his hand (from his bosom), and lo! it was white for the beholders. 108
