However, We did find many evil-doers among them. 102 Then we raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers. 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 104 Incumbent it is upon me that I speak naught respecting Allah save the truth; surely I have brought you an evidence from your Lord; wherefore let then go with me the Children of Isra'il. 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 Then [Musa (Moses)] threw his stick and behold! it was a serpent, manifest! 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
