(Az-Zukhuruf) 43 : 80
أَمْ يَحْسَبُونَ أَنَّا لَا نَسْمَعُ سِرَّهُمْ وَنَجْوَاهُمْ ۚ بَلَىٰ وَرُسُلُنَا لَدَيْهِمْ يَكْتُبُونَ
Or do they reckon that indee, We do not hear their secrets and secret talks? Nay, Our messengers with them are writing.
As explained in verses 17: 13-14, the Three-Time-Knower Lord Allah has fastened everyone’s Book of deeds around his/her neck, and all the deeds and thoughts of everyone are being recorded in it; on the Day of Judgement, everyone’s reckoning will be done by reading that Book. But the Arabic Quran-reading Fujjar who have not transformed their Jinn comrade into a believer, as explained in verses 43: 36-37, are not aware of that Book of deeds. See explanation 50: 18; 18: 49; and 82: 11-12.
