Is it not plain to those who inherit the earth after its inhabitants that if We willed We could smite them for their sins and set a seal upon their hearts, so that they do 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 We did not find the covenant upheld by the majority of them, but We found most of them evildoers. 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 all Being, 104 worthy to say nothing regarding God except the truth. I have brought a clear sign to you from your Lord; so send forth with me the Children of Israel.' 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 And he drew out his hand, and behold! it was white to all beholders! 108
