The Prophet ﷺ said: Then you, Khuza'ah, have killed this man of Hudhayl, but I will pay his blood-wit. After these words of mine if a man of anyone is killed, his people will have a choice to accept blood-wit or to kill him.
قَالَ رَسُولُ اللَّهِ ﷺ أَلاَ إِنَّكُمْ يَا مَعْشَرَ خُزَاعَةَ قَتَلْتُمْ هَذَا الْقَتِيلَ مِنْ هُذَيْلٍ وَإِنِّي عَاقِلُهُ فَمَنْ قُتِلَ لَهُ بَعْدَ مَقَالَتِي هَذِهِ قَتِيلٌ فَأَهْلُهُ بَيْنَ خِيرَتَيْنِ أَنْ يَأْخُذُوا الْعَقْلَ أَوْ يَقْتُلُوا
