Sayyiduna Abu Tha'labah (may Allah be pleased with him) said: I asked the Messenger of Allah (peace and blessings be upon him): "Give me a ruling about my bow." He (peace and blessings be upon him) said: "Eat what your bow brings back to you." I said: "Even if it disappears from me?" He (peace and blessings be upon him) said: "Even if the game stays out of your sight, provided you see no mark in it other than that of your arrow, or (as long as) it has not gone bad."
The Shaykh said: Meat whose smell has changed is not forbidden to eat, because it is reported from the Prophet (peace and blessings be upon him) that he ate fat whose smell had changed.
