يَوْمَ يَبْعَثُهُمُ ٱللَّهُ جَمِيعًۭا فَيُنَبِّئُهُم بِمَا عَمِلُوٓا۟ ۚ أَحْصَىٰهُ ٱللَّهُ وَنَسُوهُ ۚ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ شَهِيدٌ
On the day when Allah will raise them all together and inform them of what they did. Allah hath kept account of it while they forgot it. And Allah is Witness over all things.
