Consider, how terrible the end of the evil-doers is! 103 Moses told the Pharaoh, "I am a Messengers from the Lord of the Universe. 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 Then Moses threw down his staff and suddenly, unmistakably, it appeared as a serpent, 107 Then he drew out his hand and it was luminous to the onlookers. 108
