Sayyiduna Abu Rafi' (may Allah be pleased with him) said: "I slaughtered a goat for the Messenger of Allah (peace and blessings be upon him). He (peace and blessings be upon him) ordered me, so I prepared something for him from its belly. He (peace and blessings be upon him) ate from it, then stood up, prayed and did not perform ablution."
