It was narrated that Yahya bin Zurarah bin Karim bin Al-Harith bin 'Amr Al-Bahili said: "I heard my father say, that he heard his grandfather Al-Harith bin 'Amr, that he met the Messenger of Allah during the Farewell Pilgrimage, when he was atop his slit-eared camel. (He said): 'I said: O Messenger of Allah, May my father and mother be ransomed for you; pray for forgiveness for me. He said: May Allah forgive you (plural). Then I came to him from the other side, hoping that he would supplicate just for me alone, and not them. I said: O Messenger of Allah, pray for forgiveness for me. He said: May Allah forgive you (plural). Then a man among the people said: O Messenger of Allah, (what about) the 'Atirah and Fara'? He said: Whoever wishes to offer and 'Atirah may do so, and whoever does not wish to, may not. Whoever wishes to offer a Fara' may do so, and whoever does not wish to, may not. And with regard to sheep, a sacrifice should be offered. And he clasped between his fingers except for one."'
