Translation of the verse 19 from Surah AT-Tur : Number of verses 49 - - page 524 - Part 27.
"Eat and drink with happiness because of what you used to do."
[They will be told], "Eat and drink in satisfaction for what you used to do."
(52:19) (They will be told): 'Eat and drink to your hearts' *13 content as a reward for your deeds.'
*13) Here, the word "with relish" contains vast meaning in itself. In Paradise whatever a man receives, he will have it without any labor and toil. There will be no question of its sustenance in short supply. Man will not have to spend anything for it. It will be precisely according to his desire and choice and taste. In whatever quantity and whenever he will desire it, it will be made available. He will not be staying there as a guest that he may feel shy of asking for something, but everything will be the reward of his lifelong deeds and the fruit of his own labors. His eating and drinking anything will not cause any illness nor will he eat for satisfying hunger or for survival but only for the sake of enjoyment. Man will be able to obtain as much pleasure from it as he pleases without the fear of indigestion, and the food eaten will not produce any filth. Therefore, the meaning of eating and drinking "with relish" in Paradise is much mere vast and sublime than what is understood by it in the world.
