Thus doth Allah seal up the hearts of those who reject faith. 101 And We found no covenant in most of them; and most of them We found ungodly. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 Moses said: 'Pharaoh, I am a Messenger from the Lord of the Worlds, 104 (I am) worthy of not saying anything about Allah except the truth: I have come to you indeed with clear proof from your Lord, therefore send with me the children of Israel 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
