Musannaf Ibn Abi Shaybah 516 — Ablution after eating camel meat

Abu al-Aliyah said: Once Sayyiduna Abu Musa (may Allah be pleased with him) slaughtered a camel and fed its meat to his companions. Having eaten the meat, they began to stand up for prayer without performing ablution, so Sayyiduna Abu Musa stopped them and said: "It is all the same to me whether I walk in its dung and blood and do not perform ablution, or eat of its meat and do not perform ablution (that is, in my view the two cases are equal)."
