يَوْمَ يَبْعَثُهُمُ اللَّهُ جَمِيعًا فَيُنَبِّئُهُم بِمَا عَمِلُوا ۚ أَحْصَاهُ اللَّهُ وَنَسُوهُ ۚ وَاللَّهُ عَلَىٰ كُلِّ شَيْءٍ شَهِيدٌ أَلَمْ تَرَ أَنَّ اللَّهَ يَعْلَمُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ ۖ مَا يَكُونُ مِن نَّجْوَىٰ ثَلَاثَةٍ إِلَّا هُوَ رَابِعُهُمْ وَلَا خَمْسَةٍ إِلَّا هُوَ سَادِسُهُمْ وَلَا أَدْنَىٰ مِن ذَٰلِكَ وَلَا أَكْثَرَ إِلَّا هُوَ مَعَهُمْ أَيْنَ مَا كَانُوا ۖ ثُمَّ يُنَبِّئُهُم بِمَا عَمِلُوا يَوْمَ الْقِيَامَةِ ۚ إِنَّ اللَّهَ بِكُلِّ شَيْءٍ عَلِيمٌ
On the Day Allah resurrects them all together, He will then inform them of what they have done. Allah has kept account of it all, while they have forgotten it. For Allah is a Witness over all things. Do you not see that Allah knows whatever is in the heavens and whatever is on the earth? If three converse privately, He is their fourth. If five, He is their sixth. Whether fewer or more, He is with them wherever they may be. Then, on the Day of Judgment, He will inform them of what they have done. Surely Allah has knowledge of all things.
—Qur’an 58:6–7
وَمَا تَكُونُ فِي شَأْنٍ وَمَا تَتْلُو مِنْهُ مِن قُرْآنٍ وَلَا تَعْمَلُونَ مِنْ عَمَلٍ إِلَّا كُنَّا عَلَيْكُمْ شُهُودًا إِذْ تُفِيضُونَ فِيهِ وَمَا يَعْزُبُ عَن رَّبِّكَ مِن مِّثْقَالِ ذَرَّةٍ فِي الْأَرْضِ وَلَا فِي السَّمَاءِ وَلَا أَصْغَرَ مِن ذَٰلِكَ وَلَا أَكْبَرَ إِلَّا فِي كِتَابٍ مُّبِينٍ
Whatever you may be engaged in, whatever you may be reciting from the Qur’an, and whatever deeds you may be doing, We are witness over you when you are doing it. Nothing is hidden from your Lord even the weight of an atom on the earth or in the heaven. Neither anything smaller than that nor larger, but is written in a Clear Record.
—Qur’an 10:61
