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 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 did not find many of them faithful to their promises, and found many of them disobedient. 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 all Being, 104 worthy to say nothing regarding God except the truth. I have brought a clear sign to you from your Lord; so send forth with me the Children of Israel.' 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
