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 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 And most of them We found not (true) to their covenant, but most of them We found indeed Fasiqun (rebellious, disobedient to Allah). 102 Then We sent after them Moses with Our signs to Pharaoh and his establishment, but they were unjust toward them. So see how was the end of the corrupters. 103 And Moses said: "O Pharaoh! Verily, I am an apostle from the Sustainer of all the worlds, 104 "Proper it is for me that I say nothing concerning Allah but the truth. Indeed I have come unto you from your Lord with a clear proof. So let the Children of Israel depart along with me." 105 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 Then he drew out his hand and it was luminous to the onlookers. 108
