Does it not guide the people who inherit the land from former people that We can punish them for their sins if We will? And seal up their hearts so that they would not be able to lend an ear to words of guidance? 100 Such were the towns whose story We (thus) relate unto thee: There came indeed to them their messengers with clear (signs): But they would not believe what they had rejected before. Thus doth Allah seal up the hearts of those who reject faith. 101 We found most of them untrue to their covenants, indeed We found most of them to be defiant. 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 Universe, 104 I must only speak what is true about God. I have brought you miracles from your Lord; therefore, let the children of Israel go free". 105 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 So he cast his staff; and behold, it was a serpent manifest. 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
