أَلَمْ تَرَ أَنَّ اللَّهَ يَعْلَمُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ ۖ مَا يَكُونُ مِنْ نَجْوَىٰ ثَلَاثَةٍ إِلَّا هُوَ رَابِعُهُمْ وَلَا خَمْسَةٍ إِلَّا هُوَ سَادِسُهُمْ وَلَا أَدْنَىٰ مِنْ ذَٰلِكَ وَلَا أَكْثَرَ إِلَّا هُوَ مَعَهُمْ أَيْنَ مَا كَانُوا ۖ ثُمَّ يُنَبِّئُهُمْ بِمَا عَمِلُوا يَوْمَ الْقِيَامَةِ ۚ إِنَّ اللَّهَ بِكُلِّ شَيْءٍ عَلِيمٌ
ART THOU NOT aware that God knows all that is in the heavens and all that is on earth? Never can there be a secret confabulation between three persons without His being the fourth of them, nor between five without His being the sixth of them; and neither between less than that, or more, without His being with them wherever they may he. But in the end, on Resurrection Day, He will make them truly understand what they did: for, verily, God has full knowledge of everything.
