Is it not a guidance to those who inherit the earth after those who inhabited it that, did We will, We would smite them because of their sins, sealing their hearts so 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 found no covenant in the most part of them; indeed, We found the most part of them ungodly. 102 Then we raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers. 103 And Musa (Moses) said: "O Fir'aun (Pharaoh)! I am a Messenger from the Lord of the 'Alamin (mankind, jinns and all that exists). 104 so constituted that I cannot say anything about God but the truth. I have now come unto you with a clear evidence from your Sustainer: let, then, the children of Israel go with me!" 105 [Fir'aun (Pharaoh)] said: "If you have come with a sign, show it forth, - if you are one of those who tell the truth." 106 Then [Musa (Moses)] threw his stick and behold! it was a serpent, manifest! 107 Then he drew out his hand, and it appeared luminous to all beholders. 108
