Surah Az-Zukhruf (The Ornaments of Gold), Verse 80

اَمْ یَحْسَبُوْنَ اَنَّا لَا نَسْمَعُ سِرَّهُمْ وَنَجْوٰىهُمْ بَلٰی وَرُسُلُنَا لَدَیْهِمْ یَكْتُبُوْنَ ۟

Am yahsaboona annaa laa nasma'u sirrahum wa najwaahum; balaa wa Rusulunaa ladaihim yaktuboon

“Or do they think that We hear not their secrets and their private counsels? Indeed (We do), and Our messengers are by them, to record.”
