Abu Dawud
Purification (Kitab Al-Taharah)
Book Number: 001 / Hadith Number: 191
Narated By Muhammad b. al-Munkadir : I heard Jabir b. 'Abd Allah say : I presented bread and meat to the Prophet (may peace be upon him). He ate them and called for ablution water. He performed ablution and offered the noon (zuhr) prayer. He then called for the remaining food and ate it. He then got up and prayed and did not perform ablution.
