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 of them faithful to their promises, and found many of them disobedient. 102 Then after them, We sent Moosa with our signs to Firaun and his court members, but they did injustice to those signs; therefore see what sort of fate befell the mischievous! 103 Moses said: 'Pharaoh, I am a Messenger from the Lord of the Worlds, 104 One for whom it is right to say nothing but truth about Allah. Now have I come unto you (people), from your Lord, with a clear (Sign): So let the Children of Israel depart along with me." 105 He said: If you have come with a sign, then bring it, if you are of the truthful ones. 106 Thereupon Moses threw his rod, and suddenly it was a veritable serpent. 107 And putting his hand in his bosom, withdrew it – so it shone brightly before the beholders. 108
