However, We did find many evil-doers among them. 102 Then after them We sent Musa (Moses) with Our Signs to Fir'aun (Pharaoh) and his chiefs, but they wrongfully rejected them. So see how was the end of the Mufsidun (mischief-makers, corrupts, etc.). 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 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 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
