Sahih Muslim , Book 36, Hadith 197 (In-Book) ⓘ

Anas b. Malik reported: I visited Allah's Messenger one day and found him sitting in the company of his Companions and talking to them, and he had tied his belly with a bandage. Usama said: I am in doubt whether there was stone on that (his belly) or not. I asked some of his Companions why Allah's Messenger had bandaged his belly. They said: (He has done that to relieve) his hunger. I went to Abu Talha, the husband of Umm Sulaim, the daughter of Milhan, and said to him: Father, I saw Allah's Messenger having bandaged his belly. I asked some of his Companions (the reason of it) and they said that it was due to hunger. Abu Talha came to mv mother and said: Is there anything? She said: Yes, I have some pieces of bread with me and some dates. If Allah's Messenger comes to us alone we can feed him to his fill, but if someone comes along with him this would be insufficient for them. The rest of the hadith is the same.
