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 whatthe atirah is? It is what you call the Rajab sacrifice.
Abu Dawud said: 'Atirah has been abrogated, and this tradition is an abrogated one.
