Thus God seals up 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 raised after them Musa with Our communications to Firon and his chiefs, but they disbelieved in them; consider then what was the end of the mischief makers. 103 And Moses said: 'O Pharaoh! I am a Messenger from the Lord of the universe. 104 [Who is] obligated not to say about Allah except the truth. I have come to you with clear evidence from your Lord, so send with me the Children of Israel." 105 Pharaoh said: if you have brought a sign, then bring it forth if you are truthful.' 106 So he threw his rod, then lo! it was a clear serpent. 107 And he drew out his hand, and behold! it was white (with radiance) for the beholders. 108
