Musannaf Ibn Abi Shaybah

Hazrat Jabir narrates that we performed Hajj Tamattu' with the Noble Prophet (peace and blessings be upon him), and seven of us slaughtered one cow.

Hazrat Ibn Abbas (may Allah be pleased with both of them) narrates that if those performing Tamattu’ (Hajj) participate together in a single sacrifice (animal), it will suffice for all of them.

Hazrat Tawus says that one camel or cow is sufficient on behalf of seven people performing Tamattu.

Hazrat Ata says that for those who are prevented (from performing Hajj) and for those performing Tamattu', one camel is sufficient on behalf of seven persons.

According to Hasan and Hazrat Ata, there is no harm in those performing Tamattu' sharing in a she-camel or a cow.

Hazrat Sha’bah states that I asked Hazrat Hakam and Hazrat Hammad about several people sharing in one hadiy. Both of them disliked it.
