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.

I have brought a clear sign to you from your Lord; so send forth with me the Children of Israel.' 105 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 And he drew out his hand, and behold! it was white to all beholders! 108
