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 We did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient. 102 Then after them, We sent Moosa with our signs to Firaun and his court members, but they did injustice to those signs; therefore see what sort of fate befell the mischievous! 103 Moses said: "O Pharaoh, I have been sent by the Lord of all the worlds; 104 Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me. 105 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
