Translation of the verse 45 from Surah Al-Mursalat : Number of verses 50 - - page 581 - Part 29.
Woe that Day to the deniers (of the Day of Resurrection)!
Woe, that Day, to the deniers.
(77:45) Woe on that Day to those that give the lie to the Truth! *23
*23) Here this sentence means that one of their afflictions. as mentioned above, will be that they will be standing as culprits in the plain of Resurrection, their crimes will have been proved and established openly and they will not be in a position even to open their mouths to put forward a plea in self defence, and shall ultimately become fuel of Hell. Their other affliction, and by far the worse will be that they will see the same believers enjoying themselves in Paradise, whom they had been opposing and resisting and mocking throughout their lives as foolish, narrow-minded, mean and old fashioned people.
