حَدَّثَنَا يَحْيَى بْنُ يَحْيَى قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنِ ابْنِ شِهَابٍ عَنْ أَبِى سَلَمَةَ عَنْ أَبِى هُرَيْرَةَ أَنَّ امْرَأَتَيْنِ مِنْ هُذَيْلٍ رَمَتْ إِحْدَاهُمَا الأُخْرَى فَطَرَحَتْ جَنِينَهَا فَقَضَى فِيهِ النَّبِىُّ -صلى الله عليه وسلم- بِغُرَّةٍ عَبْدٍ أَوْ أَمَةٍ.

It was narrated from Abu Hurairah that there were two women from Hudhail, one of whom threw a stone at the other and caused her to miscarry. The Prophet (s.a.w) ordered that a slave, male or female, be given as Diyah.
