It is narrated from Sayyiduna Abu Waqid al-Laythi (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whatever part (of flesh and the like) is cut from a living animal while it is alive is carrion (in its ruling)." This hadith is sahih (authentic) on the condition of Imam Bukhari, and the two Shaykhs did not record it.

It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) was asked about the humps of camels and the fat tails of sheep (which used to be cut off while the animals were alive), and he (peace and blessings be upon him) said: "Whatever is cut from a living (creature) is carrion." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), and they did not record it.
