Sayyiduna Abu Rafi' (may Allah be pleased with him) said: "I was with the Messenger of Allah (peace and blessings be upon him) when he (peace and blessings be upon him) passed by a cooking pot belonging to one of his family members in which meat was cooking. Someone handed him (peace and blessings be upon him) a shoulder from it, and he (peace and blessings be upon him) ate it while standing, then prayed and did not perform ablution."
