Almuntakhab Fi Tafsir Alquran Alkarim

The Day Allahs enemies are forced to move on in throngs toward Hell, then those in the foremost lines are stopped until those in the rear catch up

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(41:19) Imagine the Day when Allah's enemies will be mustered to the Fire, *23 and the people of the former times will be detained until the arrival of people of the later times, *24

And [mention, O Muhammad], the Day when the enemies of Allah will meaning

*23) What is meant to be said have is: "When they will be rounded up to be presented in the Court of Allah," though the words used are to the effect: "When they will be gathered to be driven to Hell," for Hell in any case will be their final destination.
*24) That is, All the former and latter generations and races will be gathered together at a time and called to account together, For whatever a person does in his lifetime, whether good yr evil, its influence and impact dces not end with his life; but continues to operate even after his death for long periods of time, for which he is totally responsible. Likewise, whatever a generation does in its own time, its influence continues to affect the later generations for. centuries, and it is responsible for its heritage. It is inevitable to examine All these influences and their results and to collect their evidences. For that very reason, generation after generation of the people will go on arriving and will be withheld. The Court will start its work when All the former and latter generations will have assembled together in the Plain of Resurrection. (For further explanation, see AI-A'raf: 3839 and E.N. 30 on it).
