Imam Malik's Muwatta, Chapter: Hajj

Yahya related to me from Malik from Nafi from Abdullah ibn Umar that when he brought an animal to be sacrificed from Madina he would garland it and brand it at Dhu'l-Hulayfa, doing the garlanding before the branding, but doing both in the same place, while facing the qibla. He would garland the animal with two sandals and brand it on its left side. It would then be driven with him until he observed the standing together with everybody at Arafa. Then he would drive it on with him when everybody else moved on, and then when he arrived at Mina on the morning of the sacrifice, he would sacrifice the animal, before he shaved his head. He would sacrifice the animals with his own hands ,lining them up standing and facing the qibla. He would then eat some of the meat, and give some of it away.
