It was narrated from Abu Hurairah that:there were two women of Hudhail during the time of the Messenger of Allah, one of whom threw something at the other and caused her to miscarry. The Messenger of Allah ruled that (Diyah of ) a male or female slave be paid for that.
أَخْبَرَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ، قَالَ حَدَّثَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ امْرَأَتَيْنِ، مِنْ هُذَيْلٍ فِي زَمَانِ رَسُولِ اللَّهِ صلى الله عليه وسلم رَمَتْ إِحْدَاهُمَا الأُخْرَى فَطَرَحَتْ جَنِينَهَا فَقَضَى فِيهِ رَسُولُ اللَّهِ صلى الله عليه وسلم بِغُرَّةٍ عَبْدٍ أَوْ وَلِيدَةٍ .
