Shama-il Tirmidhi Chapter 25, Hadith Number 16 (158).

Abu Hurayrah Radiyallahu ‘Anhu says: “Meat was sent to Rasulullah Sallallahu ‘Alayhi Wasallam from someone. From it the forequarter was presented to Rasulullah Sallallahu ‘Alayhi Wasallam. He loved this portion (of the meat too). Rasulullah Sallallahu ‘Alayhi Wasallam tore the meat with his teeth and ate it”. (He did not use a knife to cut it).

Commentary.
Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam has encouraged the use of the teeth to eat. It is related in the hadith, that it should be torn and eaten, because it digests properly and it is more suitable to the body.
