“A man killed (another) during the time of the Messenger of Allah ﷺ and was referred to the Prophet ﷺ. He handed him over to the victim's next of kin, but the killer said: 'O Messenger of Allah ﷺ, by Allah I did not mean to kill him.' The Messenger of Allah ﷺ said to the next of kin, 'If he is telling the truth and you kill him, you will go to Hell.' So he let him go. He had been tied with a rope, and he went out dragging his rope, so he became known as Dhan-Nis'ah (the one with the rope).  

قَتَلَ رَجُلٌ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فَرُفِعَ ذَلِكَ إِلَى النَّبِيِّ ﷺ فَدَفَعَهُ إِلَى وَلِيِّ الْمَقْتُولِ فَقَالَ الْقَاتِلُ يَا رَسُولَ اللَّهِ وَاللَّهِ مَا أَرَدْتُ قَتْلَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ لِلْوَلِيِّ أَمَا إِنَّهُ إِنْ كَانَ صَادِقًا ثُمَّ قَتَلْتَهُ دَخَلْتَ النَّارَ قَالَ فَخَلَّى سَبِيلَهُ قَالَ وَكَانَ مَكْتُوفًا بِنِسْعَةٍ فَخَرَجَ يَجُرُّ نِسْعَتَهُ فَسُمِّيَ ذَا النِّسْعَةِ  

“A man brought the killer of his relative to the Messenger of Allah ﷺ and the Messenger of Allah ﷺ said: 'Pardon him,' but the refused. He said: 'Take the blood money,' but he refused. He said: 'Go and kill him, but then you will be like him.’ Someone caught up with him and reminded him that the Messenger of Allah ﷺ had said: 'Go and kill him, but then you will be like him.’ So he let him go. He said: So he was seen dragging his strap going to his family. He said: It seemed that he had tied him up. It's narrated that AbdurRahman bin AlQasim said "Then it is not (permissible) for anyone after the Prophet ﷺ to say 'Go and kill him, but then you will be like him.' "  

أَتَى رَجُلٌ بِقَاتِلِ وَلِيِّهِ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ النَّبِيُّ ﷺ اعْفُ فَأَبَى فَقَالَ خُذْ أَرْشَكَ فَأَبَى قَالَ اذْهَبْ فَاقْتُلْهُ فَإِنَّكَ مِثْلُهُ قَالَ فَلُحِقَ بِهِ فَقِيلَ لَهُ إِنَّ رَسُولَ اللَّهِ ﷺ قَدْ قَالَ اقْتُلْهُ فَإِنَّكَ مِثْلُهُ فَخَلَّى سَبِيلَهُ قَالَ فَرُئِيَ يَجُرُّ نِسْعَتَهُ ذَاهِبًا إِلَى أَهْلِهِ قَالَ كَأَنَّهُ قَدْ كَانَ أَوْثَقَهُ قَالَ أَبُو عُمَيْرٍ فِي حَدِيثِهِ قَالَ ابْنُ شَوْذَبٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ فَلَيْسَ لأَحَدٍ بَعْدَ النَّبِيِّ ﷺ أَنْ يَقُولَ اقْتُلْهُ فَإِنَّكَ مِثْلُهُ قَالَ ابْنُ مَاجَهْ هَذَا حَدِيثُ الرَّمْلِيِّينَ لَيْسَ إِلاَّ عِنْدَهُمْ
