I am a Messenger from the Lord of the universe. 104 Approved upon condition that I speak concerning Allah nothing but the truth. I come unto you (lords of Egypt) with a clear proof from your Lord. So let the Children of Israel go with me. 105 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 And he drew forth his hand (from his bosom), and lo! it was white for the beholders. 108
