"Some meat from the shoulder of a sheep was brought to the Messenger of Allah and he ate some of it, then he performed prayer without touching water (for ablution)."
Sunan Ibn Majah Book 1, Hadith 225
← Previous Hadith "I had dinner with Walid or Abdul-Malik. When the time for prayer came, I got up to perform ablution. Ja'far bin 'Amr bin Umayyah said: 'I bear witness that my father bore witness, that the Messenger of Allah ate food that had been changed by fire, then he performed prayer, and he did not perform ablution.' (Sahih)

And 'Ali bin 'Abdullah bin 'Abbas said: 'And I bear witness to similar from my father.'"

Sunan Ibn Majah Book 1, Hadith 224 Next 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."
