Is it not clear to those who inherit the earth in succession from its (previous) possessors, that had We willed, We would have punished them for their sins. And We seal up their hearts so that they hear not? 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 most of them untrue to their covenants, indeed We found most of them to be defiant. 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 Moses said, "O Pharaoh, 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 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And putting his hand in his bosom, withdrew it – so it shone brightly before the beholders. 108
