(Az-Zukhuruf) 43 : 80
أَمْ يَحْسَبُونَ أَنَّا لَا نَسْمَعُ سِرَّهُمْ وَنَجْوَاهُمْ ۚ بَلَىٰ وَرُسُلُنَا لَدَيْهِمْ يَكْتُبُونَ
Or do they reckon that indeed We are not hearing 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 deed on his/her neck, and all the deeds and thoughts of everyone are being recorded in it, and on the Day of Judgement everyone’s reckoning will be done by reading that book. But the Arabic Qur’an reading Fujjar who have not transformed their Jinn comrade in to 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.
