Has it not, then, become plain to those who have inherited the earth in the wake of the former generations that, had We so willed, We could have afflicted them for their sins, (they, however, are heedless to basic facts and so) We seal their hearts so that they hear nothing. 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 found most of them not true to their words; and indeed We found most of them disobedient. 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 am a messenger from the Lord of the worlds,- 104 worthy to say nothing regarding God except the truth. I have brought a clear sign to you from your Lord; so send forth with me the Children of Israel.' 105 He said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 So he cast his staff; and behold, it was a serpent manifest. 107 And he drew out his hand; thereupon it was white [with radiance] for the observers. 108
