Does it not guide the people who inherit the land from former people that We can punish them for their sins if We will? And seal up their hearts so that they would not be able to lend an ear to words of guidance? 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 no covenant in the most part of them; indeed, We found the most part of them ungodly. 102 After those We sent forth Moses with Our signs to Pharaoh and his assembly, but with it they harmed. Look at 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 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 Then Moses threw down his staff and suddenly, unmistakably, it appeared as a serpent, 107 And he drew forth his hand, and lo! it was white to the beholders. 108
