Sahih Muslim Book 23, Hadith Number 5005.

Chapter : Etiquette relating to eating and drinking.

Hudhaifa b. al-Yaman reported: When we were invited to a dinner with Allah’s Messenger (may peace be upon him); the rest of hadith is the same but there is a slight variation of wording (and the variation is) that in that hadith the desert Arab precedes the arrival of that girl, and at the conclusion there is an addition (to this effect): “He (the Holy Prophet) then mentioned the name of Allah and ate.” This hadith is reported on the authority of A’mash with the same chain of transmitters but with a slight variation of wording.
