Their Messengers came to them with clear proofs, yet they would not believe what they had belied before; as such Allah seals the hearts of the unbelievers. 101 We found most of them untrue to their covenants, indeed We found most of them to be defiant. 102 After the time of those people, We sent Moses with Our miracles to Pharaoh and his people, but they too rejected Our miracles. Consider, how terrible the end of the evil-doers is! 103 And Musa said: O Firon! surely I am an apostle from the Lord of the worlds: 104 One for whom it is right to say nothing but truth about Allah. Now have I come unto you (people), from your Lord, with a clear (Sign): So let the Children of Israel depart along 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, when lo: it was white unto the beholders. 108
