Is it not plain to those who inherit the earth after its inhabitants that if We willed We could smite them for their sins and set a seal upon their hearts, so that they do not hear. 100 We have told you the stories of those towns: their messengers came to them with clear signs, but they were never going to believe in something they had already rejected. Thus God seals up the hearts of those who deny the truth. 101 We did not find the covenant upheld by the majority of them, but We found most of them evildoers. 102 Then after them We sent Moses with Our signs to Pharaoh and his chiefs, but they wrongfully rejected them: So see what was the end of those who made mischief. 103 Moses said: "O Pharaoh, I have been sent by the Lord of all the worlds; 104 incumbent upon me is that I say nothing of Allah except the truth. I bring you a clear proof from your Lord. So let the Children of Israel depart with me' 105 Said he, 'If thou hast brought a sign, produce it, if thou speakest truly.' 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
