But We seal over their hearts so they do not hear. 100 Those cities - We relate to you, [O Muhammad], some of their news. And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers. 101 We found no covenant in the most part of them; indeed, We found the most part of them ungodly. 102 After them We sent Moses with Our signs to Pharaoh and his chiefs. But they willfully rejected them. Consider the end of the evil-doers. 103 Moses said: 'Pharaoh, I am a Messenger from the Lord of the Worlds, 104 And it behoves me to say nothing about Allah except what is true. I have come to you with a clear sign of having been sent from your Lord. So let the Children of Israel go with me.' 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 So he cast his staff; and behold, it was a serpent manifest. 107 Then he drew out his hand and it was luminous to the onlookers. 108
