The Messenger of Allah ate meat from the shoulder of a sheep, then he rinsed his mouth and washed his hands, then he prayed.
Sunan Ibn Majah Book 1, Hadith 227
← Previous Hadith They went out with the Messenger of Allah to Khaibar. When they reached As-Sahba' (a place near Khaibar), he performed 'Asr (Afternoon prayer), then he called for food, but no food was brought except for Sawiq. So they ate that and drank, and then he called for water and rinsed his mouth, then he stood up and led us for Maghrib (Sunset) prayer."

Sunan Ibn Majah Book 1, Hadith 226 Next Hadith → "The Messenger of Allah was asked about performing ablution after eating camel meat. He said: 'Perform ablution after eating it.'"
