At Tawbah, 78 Ayah
9:78
أَلَمۡ يَعۡلَمُوٓاْ أَنَّ ٱللَّهَ يَعۡلَمُ سِرَّهُمۡ وَنَجۡوَىٰهُمۡ وَأَنَّ ٱللَّهَ عَلَّٰمُ ٱلۡغُيُوبِ ٧٨
'Alam Ya`lamū 'Anna Al-Laha Ya`lamu Sirrahum Wa Najwāhum Wa 'Anna Al-Laha `Allāmu Al-Ghuyūbi
Did they not know that Allah knows their secrets and their private conversations and that Allah is the Knower of the unseen?
