عَنْ حَمْلِ بْنِ النَّابِغَةِ رَضِيَ اللَّهُ عَنْهُ قَالَ كُنْتُ بَيْنَ بَيْتَيْ امْرَأَتَيَّ فَضَرَبَتْ إِحْدَاهُمَا الْأُخْرَى بِمِسْطَحٍ فَقَتَلَتْهَا وَجَنِينَهَا فَقَضَى النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فِي جَنِينِهَا بِغُرَّةٍ وَأَنْ تُقْتَلَ بِهَا
It is narrated from Sayyiduna Haml bin Nabighah (may Allah be pleased with him), he says: I was between the houses of my two wives, one of them struck the other with a stick, as a result of which that woman died and her unborn child was also lost. The Noble Prophet (peace and blessings be upon him) decided that for the unborn child, a slave man or woman would be given, and the woman (who struck) would be killed in retribution.
