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 These towns-- We relate to you some of their stories, and certainly their apostles came to them with clear arguments, but they would not believe in what they rejected at first; thus does Allah set a seal over the hearts of the unbelievers 101 We found no (loyalty to any) covenant in most of them. Nay, most of them We found wrong-doers. 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 am a messenger from the Lord of the worlds,- 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 He said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And putting his hand in his bosom, withdrew it – so it shone brightly before the beholders. 108
