I set out with the intention of helping this person (Hadrat 'Ali) when Abu Bakra met me. He said: Ahnaf, where do you intend to go? I said: I intend to help the cousin of Messenger of Allah ﷺ, viz. 'Ali. Thereupon he said to me: Ahnaf, go back, for I heard Messenger of Allah ﷺ as saying: When two Muslims confront one another with swords (in hand) both the slayer and the slain would be in Fire. He (Ahnaf) said: I said, or it was said: Messenger of Allah, it may be the case of one who kills. but what about the slain (why he would be put in Hell-Fire)? Thereupon he said: He also intended to kill his companion.  

مسلم:٢٨٨٨a – حَدَّثَنِي أَبُو كَامِلٍ فُضَيْلُ بْنُ حُسَيْنٍ الْجَحْدَرِيُّ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ عَنْ أَيُّوبَ وَيُونُسَ عَنِ الْحَسَنِ عَنِ الأَحْنَفِ بْنِ قَيْسٍ قَالَ

خَرَجْتُ وَأَنَا أُرِيدُ هَذَا الرَّجُلَ فَلَقِيَنِي أَبُو بَكْرَةَ فَقَالَ أَيْنَ تُرِيدُ يَا أَحْنَفُ قَالَ قُلْتُ أُرِيدُ نَصْرَ ابْنِ عَمِّ رَسُولِ اللَّهِ ﷺ يَعْنِي عَلِيًّا قَالَ فَقَالَ لِي يَا أَحْنَفُ ارْجِعْ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا تَوَاجَهَ الْمُسْلِمَانِ بِسَيْفَيْهِمَا فَالْقَاتِلُ وَالْمَقْتُولُ فِي النَّارِ قَالَ فَقُلْتُ أَوْ قِيلَ يَا رَسُولَ اللَّهِ هَذَا الْقَاتِلُ فَمَا بَالُ الْمَقْتُولِ قَالَ إِنَّهُ قَدْ أَرَادَ قَتْلَ صَاحِبِهِ

One enters Hellfire if he dies while intending to kill the other

bukhari:31 – ʿAbd al-Raḥman b. al-Mubārak > Ḥammād b. Zayd > Ayyūb And Yūnus > al-Ḥasan > al-Aḥnaf b. Qays

While I was going to help this man ('Ali Ibn Abi Talib), Abu Bakra met me and asked, "Where are you going?" I replied, "I am going to help that person." He said, "Go back for I have heard Messenger of Allah ﷺ saying, 'When two Muslims fight (meet) each other with their swords, both the murderer as well as the murdered will go to the Hell-fire.' I said, 'O Messenger of Allah ﷺ! It is all right for the murderer but what about the murdered one?' Messenger of Allah ﷺ replied, "He surely had the intention to kill his companion."  

البخاري:٣١ – حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ الْمُبَارَكِ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ حَدَّثَنَا أَيُّوبُ وَيُونُسُ عَنِ الْحَسَنِ عَنِ الأَحْنَفِ بْنِ قَيْسٍ قَالَ

ذَهَبْتُ لأَنْصُرَ هَذَا الرَّجُلَ فَلَقِيَنِي أَبُو بَكْرَةَ، فَقَالَ: أَيْنَ تُرِيدُ؟ قُلْتُ: أَنْصُرُ هَذَا الرَّجُلَ۔ قَالَ: ارْجِعْ، فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ: «إِذَا الْتَقَى الْمُسْلِمَانِ بِسَيْفَيْهِمَا فَالْقَاتِلُ وَالْمَقْتُولُ فِي النَّارِ۔» فَقُلْتُ: يَا رَسُولَ اللَّهِ، هَذَا الْقَاتِلُ، فَمَا بَالُ الْمَقْتُولِ؟ قَالَ: «إِنَّهُ كَانَ حَرِيصًا عَلَى قَتْلِ صَاحِبِهِ۔»

I went to help that man (i.e., ʿAli), and on the way I met Abu Bakra who asked me, "Where are you going?" I replied, "I am going to help that man." He said, "Go back, for I heard Messenger of Allah ﷺ saying, 'If two Muslims meet each other with their swords then (both) the killer and the killed one are in the (Hell) Fire.' I said, 'O Messenger of Allah ﷺ! It is alright for the killer, but what about the killed one?' He said, 'The killed one was eager to kill his opponent."

I came out with the intention of (participating in) fighting. Abu Bakrah met me and said: Go back, for I heard the Messenger of Allah ﷺ say: When two Muslims face each other with their swords, the killer and the slain will go to Hell. He asked: Messenger of Allah, this is the killer (so naturally he should go to Hell), but what is the matter with the slain ? He replied: He intended to kill his companion.

خَرَجْتُ وَأَنَا أُرِيدُ يَعْنِي فِي الْقِتَالِ فَلَقِيَنِي أَبُو بَكْرَةَ فَقَالَ ارْجِعْ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا تَوَاجَهَ الْمُسْلِمَانِ بِسَيْفَيْهِمَا فَالْقَاتِلُ وَالْمَقْتُولُ فِي النَّارِ قَالَ يَا رَسُولَ اللَّهِ هَذَا الْقَاتِلُ فَمَا بَالُ الْمَقْتُولِ قَالَ إِنَّهُ أَرَادَ قَتْلَ صَاحِبِهِ

"I heard the Messenger of Allah [SAW] say: 'If two Muslims confront each other with their swords and one of them kills the other, both the killer and the slain will be in Hell.'" They said: "O Messenger of Allah, (we understand about) the killer, but what about the one who is killed?" He said: "He wanted to kill his companion." (Using translation from Nasāʾī 4122)
