Qur'an 4:108

يَسْتَخْفُونَ مِنَ ٱلنَّاسِ وَلَا يَسْتَخْفُونَ مِنَ ٱللَّهِ وَهُوَ مَعَهُمْ إِذْ يُبَيِّتُونَ مَا لَا يَرْضَىٰ مِنَ ٱلْقَوْلِ ۚ وَكَانَ ٱللَّهُ بِمَا يَعْمَلُونَ مُحِيطًا

“They conceal [their evil intentions and deeds] from the people, but they cannot conceal [them] from Allāh, and He is with them [in His knowledge] when they spend the night in such as He does not accept of speech. And ever is Allāh, of what they do, encompassing.”
