This hadeeth comes under the following chapter: PERTAINING TO THE MARRIAGE OF ZAINAB BINT JAHSH WITH THE HOLY PROPHET (SALLALLAAHU ALAYHI WA SALLAM) AND VERSES PERTAINING TO PURDAH (VEIL)
Anas b. Malik (Allaah be pleased with him) reported: Allaah's Messenger (sallAllaahu alayhi wa sallam) gave no better wedding feast than the one he did (on the occasion of his marriage with) Zainab. Thabit al-Bunani (one of the narrators) said: What did he serve in the wedding feast? He (Anas) said: He fed them bread and meat (so lavishly) that they (the guests) abandoned it (of their own accord after having taken them to their hearts' content).
