And there came indeed to them their Messengers with clear proofs, but they were not such as to believe in that which they had rejected before. Thus Allah does seal up the hearts of the disbelievers (from each and every kind of religious guidance). 101 We did not find many among them keeping their promises. However, We did find many evil-doers among them. 102 So We sent Moses with miracles after (these apostles) to the Pharaoh and his nobles, but they behaved with them high-handedly. See then the end of the authors of evil. 103 And Moses said, "O Pharaoh, I am a messenger from the Lord of the worlds 104 (I am) worthy of not saying anything about Allah except the truth: I have come to you indeed with clear proof from your Lord, therefore send with me the children of Israel 105 [Pharaoh] said, "If you have come with a sign, then bring it forth, if you should be of the truthful." 106 Then Moses threw down his staff and suddenly, unmistakably, it appeared as a serpent, 107 And putting his hand in his bosom, withdrew it – so it shone brightly before the beholders. 108
