A man was killed in the lifetime of the Prophet ﷺ. The matter was brought to the Prophet ﷺ. He entrusted him to the legal guardian of the slain. The slayer said: Messenger of Allah, I swear by Allah, I did not intend to kill him. The Messenger of Allah ﷺ said to the legal guardian: Now if he is true and you kill him, you will enter Hell-fire. So he let him go. His hands were tied with a strap. He came out pulling his strap. Hence he was called Dhu an-Nis'ah (possessor of strap).  

قُتِلَ رَجُلٌ عَلَى عَهْدِ النَّبِيِّ ﷺ فَرُفِعَ ذَلِكَ إِلَى النَّبِيِّ ﷺ فَدَفَعَهُ إِلَى وَلِيِّ الْمَقْتُولِ فَقَالَ الْقَاتِلُ يَا رَسُولَ اللَّهِ وَاللَّهِ مَا أَرَدْتُ قَتْلَهُ قَالَ 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 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'."  

قُتِلَ رَجُلٌ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فَدُفِعَ الْقَاتِلُ إِلَى وَلِيِّهِ فَقَالَ الْقَاتِلُ يَا رَسُولَ اللَّهِ وَاللَّهِ مَا أَرَدْتُ قَتْلَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ أَمَا إِنَّهُ إِنْ كَانَ صَادِقًا فَقَتَلْتَهُ دَخَلْتَ النَّارَ فَخَلَّى عَنْهُ الرَّجُلُ قَالَ وَكَانَ مَكْتُوفًا بِنِسْعَةٍ قَالَ فَخَرَجَ يَجُرُّ نِسْعَتَهُ قَالَ فَكَانَ يُسَمَّى ذَا النِّسْعَةِ  

“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).
