Musannaf Ibn Abi Shaybah

Hazrat Abu Alia narrates that once Hazrat Abu Musa slaughtered a camel and fed its meat to his companions. After eating the meat, those companions were about to stand for prayer without performing ablution, so Hazrat Abu Musa stopped them and said, "I believe that if I walk on its dung and blood, I would still perform ablution, and if I eat its meat, I would still perform ablution (as if, in my view, performing ablution is necessary in both situations)."
