Sufyan bin 'Uyaynah سفيان بن عيينة · The Book of al-Fara' and al-'Atirah

"While we were standing with the Messenger of Allah at 'Arafat, he said: 'O people, it is upon each family to offer a sacrifice (Udhiyah) and an 'Atirah each year." (One of the narrators) Muadh said: "Ibn 'Awn used to offer slaughter the 'Atirah, and I saw that with my own eyes during Rajab." (Daif)

"It was said to the prophet: 'During the Jahiliyyah we used to offer the 'Atirah.' He said: 'Slaughter for the sake of Allah, the Mighty and sublime, no matter what month it is; do good for the sake of Allah, the Mighty and sublime, and feed the poor."'

some men of Quraish passed by the Messenger of Allah dragging a sheep the size of a donkey. He said to them: "Why don't you take its skin?" They said: "It is dead meat." The Messenger of Allah said: "Purify it with water and Qaraz."
