سنن أبي داود

Narrated 'Aishah:

The Messenger of Allah (ﷺ) used to sacrifice goat out of every fifty goats.

Abu Dawud said: Fara' means the first baby camel born (to the Arabs). They used to sacrifice it for their idols, and then eat it, and its skin was thrown on a tree. 'Atira was a sacrifice made during the first ten days of Rajab.
