Their apostles came with clear proofs, but they did not believe what they once denied. That is how God seals the hearts of those who do not believe. 101 We found no covenant in the most part of them; indeed, We found the most part of them 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 told the Pharaoh, "I am a Messengers from the Lord of the Universe. 104 And it behoves me to say nothing about Allah except what is true. I have come to you with a clear sign of having been sent from your Lord. So let the Children of Israel go with me.' 105 He said: "If you have brought a sign then display it, if what you say is true." 106 Therefore Moosa put down his staff – it immediately turned into a visible python. 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
