"The Messenger of Allah [SAW] said: 'Whoever fights for a cause that is not clear, advocating tribalism, getting angry for the sake of tribalism, then he has died a death of Jahiliyyah.'" (Using translation from Nasāʾī 4115)
قَالَ رَسُولُ اللهِ ﷺ «مَنْ قُتِلَ تَحْتَ رَايَةٍ عُمِّيَّةٍ يُقَاتِلُ عَصَبَةً وَيَغْضَبُ لِعَصَبَةٍ فَقِتْلَتُةُ جَاهِلِيَّةٌ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ عِمْرَانُ الْقَطَّانُ لَيْسَ بِالْقَوِيِّ
