A group who wound one another's heads

Simak said that Abd al-Rahman bin al-Qa'qa' said: I invited some people to my house. They ate, drank wine and became intoxicated, and they took up the knives in the house. Then, causing an uproar with them, some of them wounded others. They were four people in all; two died and two survived. So Sayyiduna Ali (may Allah be pleased with him) made the blood money binding upon all four of them and reduced it for the wounded by the extent of the wounds they had received.

Amir said: Two men were brought to Sayyiduna al-Hasan bin Ali (may Allah be pleased with him) who had killed three people, while they themselves were both wounded. Regarding this, Sayyiduna al-Hasan bin Ali (may Allah be pleased with him) said: The blood money of the three slain is binding upon these two men, and it will be reduced for them by the extent of the wounds of the two men.

Ibn Jurayj said that Ata and Ibn Abi Mulaykah said: If a man killed someone and the slain man had wounded the killer, the killer is to be killed in retaliation, and the family of the slain man will pay the blood money for the killer's wound.

Mughirah said that Ibrahim said: Some slain and wounded people were found in a house, and the blood money of some of them was placed upon others.

Al-Shaybani said that al-Sha'bi said: Some people set out from the tribe of Zurarah and fought among themselves, and some of them killed others. Sayyiduna Ali (may Allah be pleased with him) held them liable for the blood money of the slain and reduced it for the wounded by the extent of their wounds.
