And seal up their hearts so that they would not be able to lend an ear to words of guidance? 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 did not find the covenant upheld by the majority of them, but We found most of them evildoers. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 104 [Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel." 105 Said Firaun, “If you have come with a sign, then present it if you are truthful!” 106 At this Moses threw down his staff, and lo, it became a live serpent. 107 And he drew forth his hand (from his bosom), and lo! it was white for the beholders. 108
