At-Tawbah 9:78
أَلَمْ يَعْلَمُوٓا۟ أَنَّ ٱللَّهَ يَعْلَمُ سِرَّهُمْ وَنَجْوَىٰهُمْ وَأَنَّ ٱللَّهَ عَلَّـٰمُ ٱلْغُيُوبِ
Alam yaAAlamoo anna Allaha yaAAlamusirrahum wanajwahum waanna Allaha AAallamualghuyoob
Did they not know that Allāh knows their secrets and their private conversations and that Allāh is the Knower of the unseen?
Do they not know that Allah knows what they conceal and what they whisper, and that Allah is well aware of all the Unseen?
