I am a Messenger from the Lord of the 'Alamin (mankind, jinns and all that exists). 104 "I am duty bound to speak nothing of God but the truth I have brought from your Lord a clear sign; so let the people of Israel depart with me." 105 (Pharaoh) said: "If indeed thou hast come with a Sign, show it forth,- if thou tellest the truth." 106 Then he flung down his staff and lo! it was a serpent manifest; 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
