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 did not find the covenant upheld by the majority of them, but We found most of them evildoers. 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 And Musa said: O Fir'awn! I am an apostle 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 (Pharaoh) said: "If indeed thou hast come with a Sign, show it forth,- if thou tellest the truth." 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 And he drew forth his hand, and lo, it was white to the beholders. 108
