Surah At-Tawbah, Verse 78

أَلَمۡ يَعۡلَمُوٓاْ أَنَّ ٱللَّهَ يَعۡلَمُ سِرَّهُمۡ وَنَجۡوَىٰهُمۡ وَأَنَّ ٱللَّهَ عَلَّٰمُ ٱلۡغُيُوبِ٧٨

alam yaʿlamū anna l-laha yaʿlamu sirrahum wanajwāhum wa-anna l-laha ʿallāmu l-ghuyūbi

Did they not know that Allāh knows their secrets and their private conversations and that Allāh is the Knower of the unseen?
