Mishkat al-Masabih #3513

Abu Huraira told that he heard God’s Messenger say, “He who abandons obedience and separates from the community and then dies, will die like those of pre-Islamic times; he who fights under a banner of ignorance* showing anger in support of party spirit, or summoning people to party spirit, or helping party spirit, and then is killed will be killed like those of pre-Islamic times; and he who goes out against my people with his sword smiting the virtuous and the reprobate, not keeping away from those who are believers or observing covenants which have been made, has nothing to do with me and I have nothing to do with him.” Muslim transmitted it. *'Immiya, or 'ummiya, meaning either pride or error. I have translated it as ‘‘ignorance, for it is explained as being here used of people who fight without considering whether they are in the right or not.
