Jami` at-Tirmidhi 1407
Narrated Abu Hurairah:
"A man was killed during the time of the Messenger of Allah (ﷺ), so the killer was brought to the man's guardian. The killer said: 'O Messenger of Allah! By Allah! I did not mean to kill him.' So the Messenger of Allah (ﷺ) said: 'Then if what he is saying is true, and you kill him, you would enter the Fire.' So he let the man go." He said: "His hands were bound behind him with a Nis'ah." He said: "So he left, dragging his Nis'ah." [He said:] "So he was called Dhan-Nis'ah'."
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قُتِلَ رَجُلٌ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَدُفِعَ الْقَاتِلُ إِلَى وَلِيِّهِ فَقَالَ الْقَاتِلُ يَا رَسُولَ اللَّهِ وَاللَّهِ مَا أَرَدْتُ قَتْلَهُ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ أَمَا إِنَّهُ إِنْ كَانَ صَادِقًا فَقَتَلْتَهُ دَخَلْتَ النَّارَ ‏"‏ ‏.‏ فَخَلَّى عَنْهُ الرَّجُلُ ‏.‏ قَالَ وَكَانَ مَكْتُوفًا بِنِسْعَةٍ ‏.‏ قَالَ فَخَرَجَ يَجُرُّ نِسْعَتَهُ ‏.‏ قَالَ فَكَانَ يُسَمَّى ذَا النِّسْعَةِ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏ وَالنِّسْعَةُ حَبْلٌ ‏.‏
