Shamail Tirmidhi: Hadith 180

Hazrat Jabir radiyallahu anhu says, Rasoolullah sallallahu alaihe wasallam once went to the house of a woman from among the Ansaar. I also accompanied him. The hostess slaughtered a goat for Rasoolullah sallallahu alaihe wasallam. He ate some meat from it. She then served a tray of fresh dates. Rasoolullah sallallahu alaihe wasallam ate some from it also. He then performed wudhu for Zuhr and performed the Zuhr salaah. After returning from the salaah she served from the remaining meat. Rasoolullah sallallahu alaihe wasallam ate from it. He did not perform wudhu for the Asr salaah (and performed salaah with the previous wudhu).
