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 Those cities We relate to thee tidings of; their Messengers came to them with the clear signs, but they were not the ones to believe in that they had cried lies before; so God seals the hearts of the unbelievers. 101 And We did not find for most of them any covenant; but indeed, We found most of them defiantly disobedient. 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, I am a messenger from the Lord of 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 (Pharaoh) said: If thou comest with a token, then produce it, if thou art of those who speak the truth. 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
