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 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 We found no (loyalty to any) covenant in most of them. Nay, most of them We found wrong-doers. 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 Moses said: "O Pharaoh, I have been sent by the Lord of all the worlds; 104 "I am duty bound to speak nothing of God but the truth I have brought from your Lord a clear sign; so let the people of Israel depart with me." 105 [Pharaoh] said, "If you come with a sign, then produce it, if you are telling the truth." 106 Then [Musa (Moses)] threw his stick and behold! it was a serpent, manifest! 107 And he drew out his hand, and behold! it was white (with radiance) for the beholders. 108
