Guideth it not those who inherit the land after the people thereof, that, had We willed, We would have afflicted them for their sins? And We have put a seal upon their hearts, so that they hearken not. 100 These were the (earlier) habitations whose accounts We have given to you. Their apostles came with clear proofs, but they did not believe what they once denied. That is how God seals the hearts of those who do not believe. 101 Most of them We found not men (true) to their covenant: but most of them We found rebellious and disobedient. 102 Then We sent, after them, Moses with Our signs to Pharaoh and his Council, but they did them wrong; so behold thou, how was the end of the workers of corruption! 103 And Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 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 He said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)! 107 And he drew out his hand; thereupon it was white [with radiance] for the observers. 108
