Musannaf Ibn Abi Shaybah 29470 — A man who wounds another man's head

Al-Hakam said: I sought permission from Ziyad bin Jubayr regarding Hajj, and he asked me about a man who wounded someone's head, and retaliation was then taken from him for that person, and the one from whom retaliation was taken died. I said: The one who took retaliation owes the blood money, and it will be reduced for him to the extent of the wound. Then I became apprehensive about that answer.
