Surah At-Tawbah 9:78
أَلَمْ يَعْلَمُوٓا۟ أَنَّ ٱللَّهَ يَعْلَمُ سِرَّهُمْ وَنَجْوَىٰهُمْ وَأَنَّ ٱللَّهَ عَلَّـٰمُ ٱلْغُيُوبِ
Did they not know that Allāh knows their secrets and their private conversations and that Allāh is the Knower of the unseen?
Translation: Saheeh International
Tafsir
Did they the hypocrites not know that God knows their secret what they conceal within themselves and their confidential talks what they confide in each other and that God is the Knower of the hidden things? what is concealed from the eyes.
