It is narrated from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) that some people of the Jews came to the Prophet (peace and blessings be upon him) and asked: "O Muhammad (peace and blessings be upon him)! Will there be fruits in Paradise?" He (peace and blessings be upon him) said: "Yes, in it there will be fruits, date-palms and pomegranates [Surah al-Rahman: 68]." They asked: "Then will the people of Paradise eat there just as they eat in the world?" He (peace and blessings be upon him) said: "Yes, and indeed far more than that (many times over)." They asked: "Then will they need to relieve themselves there (urine and stool)?" He (peace and blessings be upon him) said: "No; rather they will sweat and moisture will seep from their bodies, through which Allah Almighty will remove all the waste and impurities of their stomachs."
Imam Abd bin Humayd and al-Harith bin Abi Usamah recorded this hadith; its chain contains a narrator named Husayn bin Umar, who is weak and matruk (abandoned); however, the theme of the people of Paradise digesting their food through sweat and being purified of bodily impurities is established with an authentic chain in other authentic hadith (for example, Sahih Muslim: 2835).
