Sahih al-Bukhari · Book 70: Food, Meals · To seize and catch flesh with the teeth (while eating).
Narrated Ibn 'Abbas:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الْوَهَّابِ ، حَدَّثَنَا حَمَّادٌ ، حَدَّثَنَا أَيُّوبُ ، عَنْ مُحَمَّدٍ ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ تَعَرَّقَ رَسُولُ اللَّهِ صلى الله عليه وسلم كَتِفًا، ثُمَّ قَامَ فَصَلَّى، وَلَمْ يَتَوَضَّأْ .
The Prophet (ﷺ) ate of the meat of a shoulder (by cutting the meat with his teeth), and then got up and offered the prayer without performing the ablution anew.
