Musannaf Ibn Abi Shaybah

Hasan says that if two people together kill someone, then both of them have two expiations.

12866 - Muhammad ibn Yazid narrated to us from Ayyub (1) Abu al-‘Ala from Abu Hashim from Umar ﵁ (2) (he said) (3): There is only one expiation required for both of them (4).

Hazrat Sha'bi says: Do you not see that if a group of people together kill a single person, then expiation becomes obligatory upon each one of them?

It is narrated in the same way from Hazrat Sha'bi, and Hazrat Hakam also holds the same opinion.

12869 - He said: And Al-Hakam used to see that.

Ibrahim says that when a group of people kill a person (by mistake), then it is obligatory for each one of them to free a slave.

Hazrat Mak’hool says that if a group of people kill a person, then expiation is obligatory on each one of them, and blood money is due from all of them.
