Surah Al-Mujadilah Ayah 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 عَلِيمٌ ٧

Alam tara annallāha yaʿlamu mā fis-samāwāti wa mā fil-arḍ, mā yakūnu min najwā thalāthatin illā huwa rābiʿuhum wa lā khamsatin illā huwa sādisuhum wa lā adnā min dhālika wa lā akthara illā huwa maʿahum ayna mā kānū, thumma yunabbiʾuhum bimā ʿamilū yawmal-qiyāmah, innallāha bikulli shayʾin ʿalīm.

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,¹ 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.
