﴿ كُلُوا۟ وَٱشْرَبُوا۟ هَنِيٓـًٔۢا بِمَا كُنتُمْ تَعْمَلُونَ ﴾

“[and they will be told:] "Eat and drink in good cheer in return for what you did [in life]!"”

‘Eat and drink in full enjoyment hanī’an is a circumstantial qualifier in other words mutahanni’īna for what you used to do’ in the way of obedience.
