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 [Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel." 105 Said [Pharaoh]: "If thou hast come with a sign, produce it - if thou art a man of truth!" 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 and he drew forth his hand, and it appeared [shining] white to the beholders. 108
