(10) CHAPTER. If two Muslims meet (fight) each other with their swords.
Narrated Al-Hasan: (Al-Ahnaf said:) I went out carrying my arms during the nights of the affliction (i.e. the war between `Ali and `Aisha) and Abu Bakra met me and asked, Where are you going? I replied, I intend to help the cousin of Allah's Apostle (i.e.,`Ali). Abu Bakra said, Allah's Apostle said, 'If two Muslims take out their swords to fight each other, then both of them will be from amongst the people of the Hell- Fire.' It was said to the Prophet, 'It is alright for the killer but what about the killed one?' He replied, 'The killed one had the intention to kill his opponent.' (See Hadith No. 30, Vol. 1) Narrated Al-Ahnaf: Abu Bakra said: The Prophet said (as above, 204).
Narrated Hudhaifa bin Al-Yaman: The people used to ask Allah's Apostle about the good but I used to ask him about the evil lest I should be overtaken by them. So I said, O Allah's Apostle! We were living in ignorance and in an (extremely) worst atmosphere, then Allah brought to us this good (i.e., Islam); will there be any evil after this good? He said, Yes. I said, 'Will there be any good after that evil? He replied, Yes, but it will be tainted (not pure.)'' I asked, What will be its taint? He replied, (There will be) some people who will guide others not according to my tradition? You will approve of some of their deeds and disapprove of some others. I asked, Will there be any evil after that good? He replied, Yes, (there will be) some people calling at the gates of the (Hell) Fire, and whoever will respond to their call, will be thrown by them into the (Hell) Fire. I said, O Allah s Apostle! Will you describe them to us? He said, They will be from our own people and will speak our language. I said, What do you order me to do if such a state should take place in my life? He said, Stick to the group of Muslims and their Imam (ruler). I said, If there is neither a group of Muslims nor an Imam (ruler)? He said, Then turn away from all those sects even if you were to bite (eat) the roots of a tree till death overtakes you while you are in that state.
