It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever abandons obedience to the ruler and separates from the community and dies in that state, dies a death of ignorance. Whoever fights under a blind banner, becomes angry due to tribalism, calls towards tribalism, helps because of tribalism, and is killed, then he also dies a death of ignorance. And whoever comes out against my Ummah, killing the righteous and the wicked alike, does not avoid the believer, and does not fulfill the covenant of those with whom he has a covenant, then he is not from me and I am not from him."
