Is it not an indication to those who inherit the land after its people (who thus reaped the consequence of evil-doing) that, if We will, We can smite them for their sins and print upon their hearts so that they hear not? 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 many of them faithful to their promises, and found many of them disobedient. 102 Then after them We sent Moses with Our signs to Pharaoh and his chiefs, but they wrongfully rejected them: So see what was the end of those who made mischief. 103 And Moses said: "O Pharaoh! Verily, I am an apostle from the Sustainer of all the worlds, 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 indeed thou hast come with a Sign, show it forth,- if thou tellest 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 it appeared [shining] white to the beholders. 108
