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.
Sahih al-Bukhari Book 70, Hadith 32
← Previous Hadith We used to be happy on Fridays, for there was an old lady who used to pull out the roots of Silq and put it in a cooking pot with some barley. When we had finished the prayer, we would visit her and she would present that dish before us. So we used to be happy on Fridays because of that, and we never used to take our meals or have a mid-day nap except after the Friday prayer. By Allah, that meal contained no fat.

Sahih al-Bukhari Book 70, Hadith 31 Next Hadith → The Prophet (ﷺ) took out a bone with meat on it from a cooking pot and ate of it, and then offered the prayer without performing ablution anew.
