The Reward of the Righteous &the Sinners Allah informs of what the righteous will receive of delight

They are those who obeyed Allah and did not meet Him with disobedience (sins). Then He mentions that the evildoers will be in Hell and eternal torment. Due to this He says,

يَصْلَوْنَهَا يَوْمَ الدِّينِ

إِنَّ الْأَبْرَ‌ارَ‌ لَفِي نَعِيمٍ وَإِنَّ الْفُجَّارَ‌ لَفِي جَحِيمٍ (Surely the righteous will be in bliss, and surely the sinners will be in Hell,...82:13-14). These two statements are connected with verse [ 5] above: عَلِمَتْ نَفْسٌ مَّا قَدَّمَتْ وَأَخَّرَ‌تْ 'then one will know what he sent ahead and what he left behind. [ 5] '

The verse informs us that each person, on the Day of Reckoning, will know what he has done, and what will be the consequences of his deeds. The present verse says that the righteous will be in perfect bliss, while the sinners will be in a Blazing Fire of Hell.
