Al-Mujadalah 58:7 الم تر ان الله يعلم ما في السماوات وما في الارض ما يكون من نجوى ثلاثة الا هو رابعهم ولا خمسة الا هو سادسهم ولا ادنى من ذالك ولا اكثر الا هو معهم اين ما كانوا ثم ينبيهم بما عملوا يوم القيامة ان الله بكل شيء عليم ٧

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.
