It was narrated that Abu Hurairah said:“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).
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَلِيُّ بْنُ مُحَمَّدٍ، قَالاَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَتَلَ رَجُلٌ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَرُفِعَ ذَلِكَ إِلَى النَّبِيِّ صلى الله عليه وسلم فَدَفَعَهُ إِلَى وَلِيِّ الْمَقْتُولِ فَقَالَ الْقَاتِلُ يَا رَسُولَ اللَّهِ وَاللَّهِ مَا أَرَدْتُ قَتْلَهُ . فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم لِلْوَلِيِّ " أَمَا إِنَّهُ إِنْ كَانَ صَادِقًا ثُمَّ قَتَلْتَهُ دَخَلْتَ النَّارَ " . قَالَ فَخَلَّى سَبِيلَهُ . قَالَ وَكَانَ مَكْتُوفًا بِنِسْعَةٍ فَخَرَجَ يَجُرُّ نِسْعَتَهُ فَسُمِّيَ ذَا النِّسْعَةِ .
