Sahih Muslim | Book 40 | Hadith Number 6798

Narrated by Jabir
Jabir reported: I heard Allah's Apostle (may peace be upon him) as saying that the inmates of Paradise would eat and drink but would neither spit, nor pass water, nor void excrement, nor suffer catarrah. It was said: Then, what would happen with food? Thereupon he said: They would belch and sweat (and it would be over with their food), and their sweat would be that of musk and they would glorify and praise Allah as easily as you breathe.
