And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers. 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 you come with a sign, then produce it, if you are telling the truth." 106 Therefore Moosa put down his staff – it immediately turned into a visible python. 107 And he drew forth his hand, and lo! it was white to the beholders. 108
