ahya related to me from Malik from Hisham ibn Urwa that his father said, "If necessary, ride on your sacrificial animal, without burdening it, and if necessary, drink its milk after its young one has drunk its fill, and when you sacrifice it, sacrifice the young one with it."
Muwatta Malik Book 20, Hadith 148
← Previous Hadith Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to say, "If a she-camel that is being driven as a sacrificial animal gives birth, the offspring should be carried along as well and they are sacrificed together with her, and if there is no place where they can be carried, they should be carried on the mother until they are all sacrificed."

Muwatta Malik Book 20, Hadith 147 Next Hadith → 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.
