بَلْ قُلُوبُهُمْ فِي غَمْرَةٍ مِّنْ هَٰذَا وَلَهُمْ أَعْمَالٌ مِّن دُونِ ذَٰلِكَ هُمْ لَهَا عَامِلُونَ (63)
(23:63) But these people are heedless of this, *58 and their deeds are also of a different nature (from those mentioned above).
*58) They are heedless that everything they are saying and doing, is being recorded in some "book" and that they shall have to render an account of everything.
