Sharing in a sacrifice.

Qurbani = Sacrifices, - Is it permissible to sharein a sacrifice, and
how many Muslims can share in a sacrifice?.
Praise be to Allaah.
It is permissible to share in a sacrifice if it is a camel or a cow,
but it is not permissible to share in a sheep. It is permissible for
seven people to share one camel or cow.
It is narrated that the Sahaabah (may Allaah bepleased with them)
shared sacrifices: seven people would share a camel or a cow in Hajj
and 'Umrah.
Muslim (1318) narrated that Jaabir ibn 'Abd-Allaah (may Allaah be
pleased with him) said: "On the day of al-Hudaybiyah we offered the
sacrifice with the Messenger of Allaah (peace and blessings of Allaah
be upon him), a camel on behalf of seven and a cow on behalf of seven.
According to another report, it was narrated that Jaabir (may Allaah
be pleased with him) said: We performed Hajj with the Messenger of
Allaah (peace and blessings of Allaah be upon him), and we sacrificed
a camel on behalf of seven and a cow on behalf of seven.
Abu Dawood (2808) narrated from Jaabir ibn'Abd-Allaah that the Prophet
(peace and blessings of Allaah be upon him) said: "A cow on behalf of
seven and acamel on behalf of seven." Classed as saheeh by al-Albaani
in Saheeh Abi Dawood.
Al-Nawawi said in Sharh Muslim:
These ahaadeeth indicate that it is permissible to share in the
sacrifice, but they are unanimously agreed that it not permissible
toshare in a sheep. These ahaadeeth indicate that a camel is
sufficient on behalf of seven people, and a cow is sufficient on
behalf of seven people, and each of them takes the place of seven
sheep. So if a muhrim is required to offer seven sacrifices –except in
the case of the penalty for hunting –and he slaughters a camel or a
cow, that is equivalent to them all. End quote.
The Standing Committeewas asked about sharingin the sacrifice and they replied:
A camel or a cow is sufficient on behalf of seven people, whether they
are all from one family or are from different families, and whether
they are relatedto one another or not, because the Prophet (peace and
blessings of Allaah be upon him) gave permission to the Sahaabah to
share a camel or a cow, one animal for every seven people, and he did
not say anything more specific than that. End quote.
Fataawa al-Lajnah al-Daa'imah, 11/401
Shaykh Ibn 'Uthaymeen (may Allaah have mercy on him) said in Ahkaam al-Udhiyah:
One sheep is sufficient for one person, and one-seventh of a camel or
cow is sufficient for what one sheep is sufficient for. End quote.
