Thus it is that Allah seals the hearts of those who deny the truth. 101 We found no covenant in the most part of them; indeed, We found the most part of them ungodly. 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 Moses said: "O Pharaoh! I am a messenger from the Lord of the worlds,- 104 One for whom it is right to say nothing but truth about Allah. Now have I come unto you (people), from your Lord, with a clear (Sign): So let the Children of Israel depart along with me." 105 Said Firaun, “If you have come with a sign, then present it if you are truthful!” 106 Then he flung down his staff and lo! it was a serpent manifest; 107 And he drew out his hand, and behold! it was white (with radiance) for the beholders. 108
