[Machine] The Prophet ﷺ said, "Whoever kills intentionally, the blood money will be given to the heirs of the victim. If they wish, they can kill the perpetrator, or if they wish, they can accept the blood money." In the narration of Wail ibn Hujr from the Prophet ﷺ , when the killer was brought in captivity, the Messenger of Allah ﷺ asked the guardian of the victim, "Will you forgive?" He replied, "No." He then asked, "Will you take the blood money?" He replied, "No." The Prophet ﷺ then said, "Then you may kill him." He said, "Yes." The Prophet ﷺ commanded him to take him away, and this is mentioned in the chapter of forgiveness with its chain of narrators.  

أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ قَتَلَ مُتَعَمِّدًا دُفِعَ إِلَى أَوْلِيَاءِ الْقَتِيلِ فَإِنْ شَاءُوا قَتَلُوهُ وَإِنْ شَاءُوا أَخَذُوا الدِّيَةَ وَفِي حَدِيثِ وَائِلِ بْنِ حُجْرٍ عَنِ النَّبِيِّ ﷺ حِينَ جِيءَ بِالرَّجُلِ الْقَاتِلِ يُقَادُ فِي نِسْعَةٍ فَقَالَ رَسُولُ اللهِ ﷺ لِوَلِيِّ الْمَقْتُولِ أَتَعْفُو؟ قَالَ لَا قَالَ فَتَأْخُذُ الدِّيَةَ؟ قَالَ لَا قَالَ فَتَقْتُلُهُ؟ قَالَ نَعَمْ قَالَ اذْهَبْ بِهِ وَذَلِكَ فِي بَابِ الْعَفْوِ مَذْكُورٌ بِإِسْنَادِهِ
