The Messenger of Allah ﷺ said, "The people of Paradise will eat and drink in it, but they will not defecate, urinate, blow their noses, or spit. Their food will be digested as a fragrant burp and a sweat like the scent of musk."
حدثنا أبو معاوية حدثنا الأعمش عن أبي سفيان
قال رسول الله ﷺ أهل الجنة يأكلون فيها ويشربون ولا يتغوطون ولا يبولون ولا يمتخطون ولا يبزقون طعامهم جشاء ورشح كرشح المسك
Its isnad is sahih.
