Their Messengers came to them with clear proofs, yet they would not believe what they had belied before; as such Allah seals the hearts of the unbelievers. 101 We did not find most of them true to their covenants; indeed We found most of them to be transgressors. 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 duty-bound to say nothing about God but the truth, and I have brought you a clear sign from your Lord. Let the Children of Israel go with me." 105 (Pharaoh) said: "If indeed thou hast come with a Sign, show it forth,- if thou tellest the truth." 106 Thereupon he cast down his rod, when, lo it was a serpent manifest. 107 And he drew forth his hand, when lo: it was white unto the beholders. 108
