accountability and reckoning

مَـٰلِكِ يَوْمِ ٱلدِّينِ

Sovereign of the Day of Recompense.

ٱقْتَرَبَ لِلنَّاسِ حِسَابُهُمْ وَهُمْ فِى غَفْلَةٍ مُّعْرِضُونَ

[The time of] their account has approached for the people, while they are in heedlessness turning away.

فَذَرْهُمْ فِى غَمْرَتِهِمْ حَتَّىٰ حِينٍ

So leave them in their confusion for a time.
