Sahih Muslim 1850
It has been narrated on the authority of Ibn 'Abdullah al-Bajali that the Messenger of Allah ﷺ said: One who is killed under the banner of a man who is blind (to his just cause), who raises the slogan of family or supports his own tribe, dies the death of one belonging to the days of Jahiliyya.
حَدَّثَنَا هُرَيْمُ بْنُ عَبْدِ الأَعْلَى، حَدَّثَنَا الْمُعْتَمِرُ، قَالَ سَمِعْتُ أَبِي يُحَدِّثُ، عَنْ أَبِي، مِجْلَزٍ عَنْ جُنْدَبِ بْنِ عَبْدِ اللَّهِ الْبَجَلِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ
" مَنْ قُتِلَ تَحْتَ رَايَةٍ عُمِّيَّةٍ يَدْعُو عَصَبِيَّةً أَوْ يَنْصُرُ عَصَبِيَّةً فَقِتْلَةٌ جَاهِلِيَّةٌ " .
