However, We did find many evil-doers among them. 102 Then after them We sent Moses with Our signs to Pharaoh and his chiefs, but they wrongfully rejected them: So see what was the end of those who made mischief. 103 Moses said: "O Pharaoh! I am a messenger from the Lord of the worlds,- 104 incumbent upon me is that I say nothing of Allah except the truth. I bring you a clear proof from your Lord. So let the Children of Israel depart with me' 105 He said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew forth his hand (from his bosom), and lo! it was white for the beholders. 108
