I am a messenger from the Lord of the worlds,- 104 (I am) worthy of not saying anything about Allah except the truth: I have come to you indeed with clear proof from your Lord, therefore send with me the children of Israel 105 He said: "If you have brought a sign then display it, if what you say is true." 106 Then he flung down his staff and lo! it was a serpent manifest; 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
