And seal up their hearts so that they would not be able to lend an ear to words of guidance? 100 Those villages We narrate their news to you. 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 sent, after them, Moses with Our signs to Pharaoh and his Council, but they did them wrong; so behold thou, how was the end of the workers of corruption! 103 And Moses said: "O Pharaoh! Verily, I am an apostle from the Sustainer of all the worlds, 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 Then he flung down his staff and lo! it was a serpent manifest; 107 And he drew forth his hand, and behold, it looked white to those who beheld it. 108
