Thus it is that Allah seals the hearts of those who deny the truth. 101 We found most of them untrue to their covenants, indeed We found most of them to be defiant. 102 Then We sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them.

I have brought you miracles from your Lord; therefore, let the children of Israel go free". 105 (Pharaoh) said: If thou comest with a token, then produce it, if thou art of those who speak the truth. 106 So Moses threw his staff, and suddenly it was a serpent, manifest. 107 And he drew out his hand, and behold! it was white to all beholders! 108
