quran:43:80 –

Or do they think that We hear not their secrets and their private conversations? Yes, ˹We do˺, and Our messengers are with them recording.  

Or do they reckon that We do not hear their secret thoughts and their conspiring?, that is to say, what they secretly communicate to others and what they openly conspire about among themselves. Yes indeed!, We hear ˹all of˺ that, and Our messengers, the guardians, are with them keeping a record, of that.
القرآن:٤٣:٨٠ –

أَمْ يَحْسَبُونَ أَنَّا لَا نَسْمَعُ سِرَّهُمْ وَنَجْوَاهُمْ ۚ بَلَىٰ وَرُسُلُنَا لَدَيْهِمْ يَكْتُبُونَ  

{أم يحسبون أنا لا نسمع سرهم ونجواهم} ما يسرون إلى غيرهم وما يجهرون به بينهم {بلى} نسمع ذلك {ورسلنا} الحفظة {لديهم} عندهم {يكتبون} ذلك.
