2. Īmān (Faith / Belief)

٢۔ كتاب الإيمان

2.23 "And if two parties (or groups) from among the believers fall to fighting, then make peace between them both…" Allah has called them "believers"

٢۔٢٣ بَابُ: {وَإِنْ طَائِفَتَانِ مِنَ الْمُؤْمِنِينَ اقْتَتَلُوا فَأَصْلِحُوا بَيْنَهُمَا} فَسَمَّاهُمُ الْمُؤْمِنِينَ

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

bukhari:31ʿAbd 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:٣١حَدَّثَنَا 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۔»
