And certainly did their messengers come to them with clear proofs, but they were not to believe in that which they had denied before. Thus does Allah seal over the hearts of the disbelievers. 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 sent, after them, Musa with Our signs unto Fir'awn and his chiefs, but they wronged them. Behold that wise was the end of the corrupters! 103 And Moses said, "O Pharaoh, I am a messenger from the Lord of the worlds 104 incumbent upon me is that I say nothing of Allah except the truth. I bring you a clear proof from your Lord. So let the Children of Israel depart with me' 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 Thereupon Moses threw his rod, and suddenly it was a veritable serpent. 107 And he drew out his hand, and behold! it was white to all beholders! 108
