It has been narrated on the authority of Abu Hurairah (RA) that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: One who defected from obedience (to the Amir) and separated from the main body of the Muslims-if he died in that state-would die the death of one belonging to the days of Jahiliyya (i. e. would not die as a Muslim). One who fights under the banner of a people who ate blind (to the cause for which they are fighting. i. e. do not know whether their cause is just or otherwise), who gets flared up with family pride, calls, (people) to fight for their. family honour, and supports his kith and kin (i. e. fignts not for the cause of Allah but for the sake of this family or tribe) -if he is killed (in this fight), he dies as one belonging to the days of Jhiliyya. Whoso attacks my Umma (indiscriminately) killing the righteous and the wicked of them, sparing not (even) those staunch in faith and fulfilling not his promise made with those who have been given a pledge of security-he has nothing to do with me and I have nothing to do with him.

The same tradition has been narrated by the same authority through another chain of transmitters with a slight difference in wording.

It has been narrated (through a different chain of transmitters) on the authority of Abu Hurairah (RA) that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: Who defected from obedience (to the Amir) and separated from the main body of the Muslim-then he died in that state-would die the death of one belonging to the days of Jahillyya. And he who is killed under the banner of a man who is blind (to the cause for which he is fighting), who gets flared up with family pride and fights for his tribe-is not from my Umma, and whoso from my followers attacks my followers (indiscriminately) killing the righteous and the wicked of them, sparing not (even) those staunch in faith and fulfilling not his obligation towards them who have been given a pledge (of security), is not from me (i. e. is not my follower).

This hadlth has been narrated on the authority of Jarir with the same chain of transmitters with a slight variation in wording.
