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 found no covenant in most of them; and most of them We found ungodly. 102 AND AFTER those [early people] We sent Moses with Our messages unto Pharaoh and his great ones, and they wilfully rejected them: and behold what happened in the end to those spreaders of corruption! 103 And Musa said: O Firon! surely I am an apostle from the Lord of the worlds: 104 "Proper it is for me that I say nothing concerning Allah but the truth. Indeed I have come unto you from your Lord with a clear proof. So let the Children of Israel depart along with me." 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 So he cast his staff; and behold, it was a serpent manifest. 107 and he drew forth his hand, and lo! it appeared [shining] white to the beholders. 108
