AHMAD 19590:
from al-Ḥasan —
[Machine] "That a brother of Abu Musa used to hasten in discord, so he (Abu Musa) started advising him, but he did not stop. So he (Abu Musa) said: 'If I find that a little bit of admonition or preaching will be enough for you from me, or if the Messenger of Allah ﷺ said, 'When two Muslims confront each other with their swords, and one of them kills the other, then both the killer and the one killed will be in the Fire.' It was said: 'The killer is known, but what about the one killed?' He said: 'He wanted to kill his companion.'"

عن الحسن —
أَنَّ أَخًا لِأَبِي مُوسَى كَانَ يَتَسَرَّعُ فِي الْفِتْنَةِ فَجَعَلَ يَنْهَاهُ وَلَا يَنْتَهِي فَقَالَ إِنْ كُنْتُ أَرَى أَنَّ سَيَكْفِيكَ مِنِّي الْيَسِيرُ أَوْ قَالَ مِنَ الْمَوْعِظَةِ دُونَ مَا أَرَى وَإِنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا تَوَاجَهَ الْمُسْلِمَانِ بِسَيْفَيْهِمَا فَقَتَلَ أَحَدُهُمَا الْآخَرَ فَالْقَاتِلُ وَالْمَقْتُولُ فِي النَّارِ فَقِيلَ هَذَا الْقَاتِلُ فَمَا بَالُ الْمَقْتُولِ؟ قَالَ إِنَّهُ أَرَادَ قَتْلَ صَاحِبِهِ
