The Messenger of Allah ﷺ gave judgment that a male or a female slave, or a horse or a mule should be paid for a miscarriage. Abu Dawud said: Hammad b. Salamah and Khalid b. 'Abd Allah transmitted this tradition from Muhammad b. 'Amr, but they did not mention "or a horse or a mule"
قَضَى رَسُولُ اللَّهِ ﷺ فِي الْجَنِينِ بِغُرَّةٍ عَبْدٍ أَوْ أَمَةٍ أَوْ فَرَسٍ أَوْ بَغْلٍ
