Behold that wise was the end of the corrupters! 103 Moses said: "O Pharaoh, I have been sent by the Lord of all 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 answered: 'If you have come with a sign, show it to us if you are of the truthful' 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 Then he drew out his hand and it was luminous to the onlookers. 108
