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 After the time of those people, We sent Moses with Our miracles to Pharaoh and his people, but they too rejected Our miracles. Consider, how terrible the end of the evil-doers is! 103 Moses said, 'Pharaoh, I am a Messenger from the Lord of all Being, 104 Incumbent it is upon me that I speak naught respecting Allah save the truth; surely I have brought you an evidence from your Lord; wherefore let then go with me the Children of Isra'il. 105 He answered: 'If you have come with a sign, show it to us if you are of the truthful' 106 Then he flung down his staff and lo! it was a serpent manifest; 107 Then he uncovered his hand and it appeared sheer white to the onlookers. 108
