Do not the people who inherited the earth from the (earlier) inhabitants perceive that We could afflict them too for their sins if We pleased, and put seals on their hearts that they may not hear (the voice of truth)? 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 We did not find the covenant upheld by the majority of them, but We found most of them evildoers. 102 So We sent Moses with miracles after (these apostles) to the Pharaoh and his nobles, but they behaved with them high-handedly. See then the end of the authors of evil. 103 And Musa said: O Firon! surely I am an apostle from the Lord of the worlds: 104 duty-bound to say nothing about God but the truth, and I have brought you a clear sign from your Lord. Let the Children of Israel go with me." 105 (Pharaoh) said: "If indeed thou hast come with a Sign, show it forth,- if thou tellest the truth." 106 Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)! 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
