Sunan Ibn Majah Book 21, Hadith 2647

حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، أَنْبَأَنَا يَزِيدُ بْنُ هَارُونَ، أَنْبَأَنَا مُحَمَّدُ بْنُ رَاشِدٍ، عَنْ سُلَيْمَانَ بْنِ مُوسَى، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ قَضَى رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ يَعْقِلَ الْمَرْأَةَ عَصَبَتُهَا مَنْ كَانُوا وَلاَ يَرِثُوا مِنْهَا شَيْئًا إِلاَّ مَا فَضَلَ عَنْ وَرَثَتِهَا وَإِنْ قُتِلَتْ فَعَقْلُهَا بَيْنَ وَرَثَتِهَا فَهُمْ يَقْتُلُونَ قَاتِلَهَا ‏"‏ ‏.‏

It was narrated from 'Amr bin Shu'aib, from his father, that his grandfather said:“The Messenger of Allah (ﷺ) ruled that a woman's blood money (if she kills someone) should be paid by her male relatives on her father's side, whoever they are, and they should not inherit anything from her, except what is left over after her heirs have been taken their shares. If she is killed than her blood money is to be shared among her heirs, since they are the ones who may kill the one who killed her.”
