Musannaf Ibn Abi Shayba 20:51

Abu Bakr narrated to us, he said: Hafs bin Ghiyath narrated to us, from Mujalid, from al-Sha’bi, who said: A woman struck another woman and killed her, and she cast a dead fetus. He said: The Prophet, peace and blessings of Allah be upon him, decreed the blood money (diyah) upon the paternal relatives (aqilah) of the killer, and he did not place anything upon her children nor upon her husband. And he decreed the blood money for the husband of the killed woman and her children, and he did not grant her paternal relatives (asabah) anything from it.
