Sunan Abi Dawud Book 28, Hadith 45
The bone dearer to the Messenger of Allah (ﷺ) was the bone of sheep.
I was eating with the Prophet (ﷺ) and snatching the meat from the bone with my hand. He said: bring the bone near your mouth, for it is more beneficial and wholesome.
Abu Dawud said: 'Uthman did not hear (traditions) from Safwan. This is a mursal tradition.
The tradition mentioned above (No. 3771) has also been narrated by Ibn Mas'ud with a different chain of narrators.
This version has: The Prophet (ﷺ) liked the foreleg (of a sheep). Once the foreleg was poisoned, and he thought that the Jews had poisoned it.
