Narrated Al-Mughirah bin Shu'bah:"Two women co-wives, (were fighting), and one of them hit the other with a stone or a tent post, causing her to have a miscarriage. The Messenger of Allah (ﷺ) judged that a Ghurrah male or female slave should be given for fetus, and he required it from the Asabah of the woman." (Another Chain) for this Hadith [and it is similar to this]
