Narrated Mikhnaf ibn Sulaym: We were staying with the Messenger of Allah (ﷺ) at Arafat; he said: O people, every family must offer a sacrifice and an atirah. Do you know what the atirah is? It is what you call the Rajab sacrifice. Abu Dawud said: “Atirah has been abrogated, and this tradition is an abrogated one”
