Sahih Muslim Book 23, Hadith Number 5062.

Chapter : Permissibility of a person’s taking anyone along with him where the host is very intimate with the guest.

Anas b. Malik reported this incident pertaining to the feast given by Abu Talha to Allah’s Apostle (may peace be upon him) with the addition of these words: “Abu Talha stood at the door (to welcome the honourable guest) until Allah’s Messenger (may peace be upon him) came there, He (Abu Talha) said to him: Allah’s Messenger, the thing (we intend to offer you as a meal) is small in quantity. Thereupon he (the Holy Prophet) said: Bring that, for Allah will soon bless it (and increase it).
