﴿ كُلُوا۟ وَٱشْرَبُوا۟ هَنِيٓـًٔۢا بِمَآ أَسْلَفْتُمْ فِى ٱلْأَيَّامِ ٱلْخَالِيَةِ ﴾

“[And all who are thus blest will be told:] "Eat and drink with good cheer in return for all [the good deeds] that you have sent ahead in days gone by!"”

And so it will be said to them ‘Eat and drink in enjoyment hanī’an is a circumstantial qualifier that is to say mutahanni’īna ‘while you are enjoying them’ for what you did in advance in former days’ in days that have passed during the life of the world.
