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 many among them keeping their promises. However, We did find many evil-doers among them. 102 Then after them We sent Musa (Moses) with Our Signs to Fir'aun (Pharaoh) and his chiefs, but they wrongfully rejected them. So see how was the end of the Mufsidun (mischief-makers, corrupts, etc.). 103 Moses said: "O Pharaoh, I have been sent by the Lord 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 Said he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 Then he flung down his staff and lo! it was a serpent manifest; 107 And he drew out his hand, and behold! it was white to all beholders! 108
