To those who inherit the earth in succession to its (previous) possessors, is it not a guiding, (lesson) that, if We so willed, We could punish them (too) for their sins, and seal up their hearts so that they could 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 We did not find most of them true to their covenants; indeed We found most of them to be transgressors. 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 Musa said: O Fir'awn! I am an apostle from the Lord of the worlds; 104 Incumbent it is upon me that I speak naught respecting Allah save the truth; surely I have brought you an evidence from your Lord; wherefore let then go with me the Children of Isra'il. 105 Said Firaun, “If you have come with a sign, then present it if you are truthful!” 106 Therefore Moosa put down his staff – it immediately turned into a visible python. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
