Translation of the verse 24 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.
(77:24) Woe on that Day to those that give the lie to the Truth! *14
*14) This sentence here gives the meaning that in spite of the express argument for the possibility of life-after-death, the people who are denying it, may mock it as they may and look down upon its believers as people of antiquated ideas and whims, but when the Day comes which they are denying today, they will themselves know that it is a Day of their own ruin and disaster.
