﴿ 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!"”

Allah will say to them: (Eat) of the fruits (and drink) from the rivers (at ease) fearing no sickness or death (for that which ye sent on before you) for that which you did of righteous works; and it is also said this means: for the fasting and prayers you offered, (in past days) i.e. in the days of the life of the world.
