Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “Whoever withdraws from lawful obedience to the leader and divides the community and dies in this state, he will have died upon ignorance. Whoever fights under a banner of blindness, raging for the sake of tribalism, or calling to tribalism, or supporting tribalism and he is killed in this state, he will have died upon ignorance. Whoever rebels against my nation, striking the righteous and wicked alike, sparing not even their believers and he does not fulfill the pledge of security to whom it is due, he has nothing to do with me and I have nothing to do with him.”

عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ مَنْ خَرَجَ مِنَ الطَّاعَةِ وَفَارَقَ الْجَمَاعَةَ فَمَاتَ مَاتَ مِيتَةً جَاهِلِيَّةً وَمَنْ قَاتَلَ تَحْتَ رَايَةٍ عُمِّيَّةٍ يَغْضَبُ لِعَصَبَةٍ أَوْ يَدْعُو إِلَى عَصَبَةٍ أَوْ يَنْصُرُ عَصَبَةً فَقُتِلَ فَقِتْلَةٌ جَاهِلِيَّةٌ وَمَنْ خَرَجَ عَلَى أُمَّتِي يَضْرِبُ بَرَّهَا وَفَاجِرَهَا وَلاَ يَتَحَاشَ مِنْ مُؤْمِنِهَا وَلاَ يَفِي لِذِي عَهْدٍ عَهْدَهُ فَلَيْسَ مِنِّي وَلَسْتُ مِنْهُ
