Surah Az-Zukhruf, Verse 80

أَمۡ يَحۡسَبُونَ أَنَّا لَا نَسۡمَعُ سِرَّهُمۡ وَنَجۡوَىٰهُمۚ بَلَىٰ وَرُسُلُنَا لَدَيۡهِمۡ يَكۡتُبُونَ٨٠

am yaḥsabūna annā lā nasmaʿu sirrahum wanajwāhum balā warusulunā ladayhim yaktubūna

Or do they think that We hear not their secrets and their private conversations? Yes, [We do], and Our messengers [i.e., angels] are with them recording.
