Al-Mujaadila • EN-TAFSIR-MAARIF-UL-QURAN
﴿ يَوْمَ يَبْعَثُهُمُ ٱللَّهُ جَمِيعًۭا فَيُنَبِّئُهُم بِمَا عَمِلُوٓا۟ ۚ أَحْصَىٰهُ ٱللَّهُ وَنَسُوهُ ۚ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ شَهِيدٌ ﴾
“on the Day when God will raise them all from the dead and will make them truly understand all that they did [in life]: God will have taken [all of] it into account, even though they [themselves] may have forgotten it - for God is witness unto everything.”
أَحْصَاهُ اللَّـهُ وَنَسُوهُ (...Allah has its full account, while they have forgotten transgressions, but because he treats them as trivial and insignificant, he is unable to remember and recall them. However, they are all recorded and kept safely with Allah, even though the humans have done the actions and forgotten them. Allah will call them to give an account of them on the Day of Resurrection and chastise them.
