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 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, Moses with Our signs to Pharaoh and his Council, but they did them wrong; so behold thou, how was the end of the workers of corruption! 103 Moses said: O Pharaoh! Lo! I am a messenger from the Lord of the Worlds, 104 Incumbent it is upon me that I speak naught respecting Allah save the truth; surely I have brought you an evidence from your Lord; wherefore let then go with me the Children of Isra'il. 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 to all beholders! 108
