Surah Al-Mujadila, Verse 7

أَلَمۡ تَرَ أَنَّ ٱللَّهَ يَعۡلَمُ مَا فِي ٱلسَّمَٰوَٰتِ وَمَا فِي ٱلۡأَرۡضِۖ مَا يَكُونُ مِن نَّجۡوَىٰ ثَلَٰثَةٍ إِلَّا هُوَ رَابِعُهُمۡ وَلَا خَمۡسَةٍ إِلَّا هُوَ سَادِسُهُمۡ وَلَآ أَدۡنَىٰ مِن ذَٰلِكَ وَلَآ أَكۡثَرَ إِلَّا هُوَ مَعَهُمۡ أَيۡنَ مَا كَانُواْۖ ثُمَّ يُنَبِّئُهُم بِمَا عَمِلُواْ يَوۡمَ ٱلۡقِيَٰمَةِۚ إِنَّ ٱللَّهَ بِكُلِّ شَيۡءٍ عَلِيمٌ٧

Have you not considered that Allāh knows what is in the heavens and what is on the earth? There are not three in a private conversation but that He is the fourth of them, nor are there five but that He is the sixth of them - and no less than that and no more except that He is with them [in knowledge] wherever they are. Then He will inform them of what they did, on the Day of Resurrection. Indeed Allāh is, of all things, Knowing.
