الْيَوْمَ تُجْزَىٰ كُلُّ نَفْسٍ بِمَا كَسَبَتْ لَا ظُلْمَ الْيَوْمَ
Today every soul is repaid for what it earned; no injustice occurs today.
For what it earned connects recompense to the servant’s deeds, and no injustice affirms the justice of the Final Judgment. Reward and punishment are not arbitrary.
The record of deeds and their weighing are distinct parts of accountability. Treating every stage as merely another name for reckoning obscures the separate realities affirmed for the Last Day.
