﴿ عَلِمَتْ نَفْسٌۭ مَّا قَدَّمَتْ وَأَخَّرَتْ ﴾

“every human being will [at last] comprehend, what he has sent ahead and what he has held back [in this world].”

(A soul) every soul at that point (will know what it hath sent before (it)) of good or evil (and what left behind) of good or evil wont; it is also said this means: it will know the acts of obedience it offered and those it missed.
