وَجِيءَ يَوْمَئِذٍ بِجَهَنَّمَ ۚ يَوْمَئِذٍ يَتَذَكَّرُ الْإِنسَانُ وَأَنَّىٰ لَهُ الذِّكْرَىٰ (23)
(89:23) and when Hell is brought near that Day. On that Day will man understand, but of what avail will that understanding be? *17
*17) The words in the original can have two meanings:
(1) That on that Day man will remember whatever he had done in the world and will regret, but what will remembrance and regretting avail him then?
(2) That on that Day man will take heed and accept admonition: he will realize that whatever he had been told by the Prophets was true and he committed a folly when he did not listen to them; but what will taking heed and accepting the admonition and realizing one's errors avail one then ?
