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 And We did not find in most of them any (faithfulness to) covenant, and We found most of them to be certainly 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 Musa said: O Firon! surely I am an apostle from the Lord of the worlds: 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 He said: if thou hast brought a sign, forth with it then, if thou art of the truth-tellers. 106 Thereupon [Moses] threw down his staff, and lo! it was a serpent, plainly visible; 107 And he drew out his hand, and behold! it was white to all beholders! 108
