Do they not know that Allah knows what they conceal and what they disclose?
Sayyed Abbas Sadr-Ameli
What ! Do they not know that Allah knows what they hide and what they make known ?
Al-muntakhab fi tafsir al-Qur'an al-Karim
Do they not know that Allah knows what they exchange secretly or whisper and what they suggest secretly and all feelings stored in their hearts, and He is well acquainted with all they utter out loud
