Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) says that a woman struck another with a tent pole, killed her, and caused her pregnancy to be lost. So the Prophet (peace and blessings be upon him) ruled her blood money upon the woman's paternal kin ('asabah), and a male or female slave for the child. A man from the paternal kin of the woman who killed said: "How can there be blood money for one who neither cried out, nor screamed, nor ate, nor drank?" So he (peace and blessings be upon him) said: "This one is composing rhymed speech like the rural (Bedouin) poets," and he upheld the blood money upon them.
