Abu Dawud

Narrated Nubayshah: A man called the Messenger of Allah ﷺ: We used to sacrifice Atirah in pre-Islamic days during Rajab; so what do you command us? He said: Sacrifice for the sake of Allah in any month whatever; obey Allah, Most High, and feed (the people). He said: We used to sacrifice a Fara in pre-Islamic days, so what do you command us? He said: On every pasturing animal there is a Fara which is fed by your cattle till it becomes strong and capable of carrying load. The narrator Nasr said (in his version): When it becomes capable of carrying load of the pilgrims, you may slaughter it and give its meat as charity (sadaqah). The narrator Khalid's version says: You (may give it) to the travellers, for it is better. Khalid said: I asked Abu Qilabah: How many pasturing animals? He replied: One hundred.

Narrated Abu Hurairah: Prophet ﷺ sa saying: There is no Fara and 'atirah.

Narrated Saeed: Fara was the first animal born to them (the Arabs) which they sacrificed.

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.
