"And it is upon those (relatives) of the killed one to block (any punishment) the first (in line) then the first, even if that one is a woman."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ وَعَلَى الْمُقْتَتِلِينَ أَنْ يَنْحَجِزُوا الأَوَّلَ فَالأَوَّلَ وَإِنْ كَانَتِ امْرَأَةٌ  

The Prophet ﷺ Said: The disputants should refrain from taking retaliation. The one who is nearer should forgive first and then the one who is next to him, even if (the one who forgives) were a woman. Abu Dawud said: I have been informed that forgiving by women in the case of murder is permissible if a woman were one of the heirs (of the slain). I have been told on the authority of Abu 'Ubaid about the meaning of the word yanhajizu, that is, they should refrain from retaliation.  

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ عَلَى الْمُقْتَتِلِينَ أَنْ يَنْحَجِزُوا الأَوَّلَ فَالأَوَّلَ وَإِنْ كَانَتِ امْرَأَةً  

"And it is upon those (relatives) of the killed one to block (any punishment) the first (in line) then the first, even if that one is a woman." (Using translation from Nasāʾī 4788)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «وَعَلَى الْمُقْتَتِلِينَ أَنْ يَتَحَجَّزُوا الْأَوَّلَ فَالْأَوَّلَ وَإِنْ كَانَتِ امْرَأَةً»
