I heard Allah's Apostle ﷺ 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. (Using translation from Muslim 2835a)
أَنَّهُ سَمِعَ النَّبِيَّ ﷺ يَقُولُ يَأْكُلُ أَهْلُ الْجَنَّةِ فِيهَا وَيَشْرَبُونَ وَلَا يَمْتَخِطُونَ وَلَا يَتَغَوَّطُونَ وَلَا يَبُولُونَ إِنَّمَا طَعَامُهُمْ جُشَاءٌ رَشْحٌ كَرَشْحِ الْمِسْكِ وَيُلْهَمُونَ التَّسْبِيحَ وَالتَّحْمِيدَ كَمَا يُلْهَمُونَ النَّفَسَ
