Mu'jam Kabir Tabarani 510 — I heard from my father - and he was

Abu al-Malih said: I heard from my father - and he was a Companion of the Messenger of Allah (peace and blessings be upon him) - he said: There were two women (in our tribe); one of them struck the other with a piece of wood (a tent pole), so that she died, and what was in her womb (the child) also died. So the Prophet (peace and blessings be upon him) ruled blood money (diyah) for the (slain) woman, and for the fetus a ghurrah: a male slave, or a female slave, or a horse, or two camels, or such-and-such a number of sheep. Then a man from the clan of the woman who had killed said: "O Messenger of Allah! How are we to pay blood money for (a child) who neither ate, nor drank, nor cried out, nor screamed? The death of such (a child) goes unrequited." The Messenger of Allah (peace and blessings be upon him) said: "Are you speaking in rhymed prose?" And the Messenger of Allah (peace and blessings be upon him) ruled that the woman's inheritance is for her husband and her children, and that the blood money is due from the 'asabah (paternal kinsmen) of the woman who killed.
