Narrated Ibn 'Abbas: 'Umar asked about the decision of the Prophet (ﷺ) about that (i.e. abortion). Haml b. Malik b. al-Nabhigah got up and said: I was between two women. One of them struck another with a rolling-pin killing both her and what was in her womb. So the Messenger of Allah (ﷺ) gave judgement that the bloodwit for the unborn child should be a male or a female slave of the best quality and the she should be killed. Abu Dawud said: Al-Nadr b. Shumail said: Mistah means a rolling-pin. Abu Dawud said: Abu 'Ubaid said: Mistah means a pole from the tent-poles
