The Messenger of Allah ruled that the Diyah was to be paid by the 'Asabah of the killer, and that a slave should be given (as diyah) for the child in her womb. The Bedouin Said: "Are you penalizing me for one who neither ate nor drank, or shouted or cried (at the moment of birth)? Such a one should be overlooked/" He said: "Rhyming verse like the verse of the Jahiliyyah," and he ruled that a slave should e given (as Diyah) for the child in her womb
