Is it not plain to those who inherit the earth after its inhabitants that if We willed We could smite them for their sins and set a seal upon their hearts, so that 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 We found no covenant in the most part of them; indeed, We found the most part of them ungodly. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 And Moses said, "O Pharaoh, I am a messenger from the Lord of the worlds 104 One for whom it is right to say nothing but truth about Allah. Now have I come unto you (people), from your Lord, with a clear (Sign): So let the Children of Israel depart along with me." 105 He answered: 'If you have come with a sign, show it to us if you are of the truthful' 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 And he drew out his hand, and behold! it was white (with radiance) for the beholders. 108
