We were with the Prophet ﷺ at a banquet, and the foreleg was presented to him, which he particularly liked. He took a bite from it... the rest of the lengthy hadith concerns the intercession.
كنا مع النبي ﷺ في دعوة، فرفع إليه الذراع- وكانت تعجبه- فنهس منها نهسة… الحديث بطوله في الشفاعة.
Bukhari narrated it in the Book of the Prophets (3340), and Muslim in the Book of Faith (194:327), both of them through Abu Hayan, from Abu Zura, from Abu Hurairah, who said the following, then he mentioned it.Abu Hayan's name was Yahya bin Saeed bin Hayan Taymi. Abu Zura's name was Harim bin Amr bin Jareer.His statement, "he tore off a piece of it with his teeth," means he took it with the edges of his teeth.
