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 villages We narrate their news to you. Their Messengers came to them with clear proofs, yet they would not believe what they had belied before; as such Allah 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 After those We sent forth Moses with Our signs to Pharaoh and his assembly, but with it they harmed. Look at the end of the corrupters. 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 Said he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 Then (Moses) threw his rod, and behold! it was a serpent, plain (for all to see)! 107 And he drew out his hand; thereupon it was white [with radiance] for the observers. 108
