صحیح مسلم · Hadith 794

Ja'far b. 'Amr b. Umayya al-Damari reported on the authority of his father who said: I saw the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) take slices from goat's shoulder and then eat them. He was called for prayer and he got'up, leaving aside the knife, and offered prayer but did not perform ablution. Ibn 'Abbas reported it on the authority of Maimuana, the wife of the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ), that the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) took (a piece of goat's) shoulder at her place, and then offered prayer but did not perform ablution.
