That wasn't a religous manner at all. It was a matter of spreading war booty. He made a mistake in the way he talked to our nabi and didn't think of what the nabi was really doing. He made a mistake, doesn't mean the man is a khawarij or anything like that, based on that one statement.
Khawaarij came in the first Islamic civil war. None were around during the time of the prophet. You are wrong. Its ok to admit you're wrong you know. You're not gonna rewrite history now.
Surely if there were khawarij during the time of the nabi he would have told us these men are khawarij but he never did. Everything he mentioned about khawarij was there will come...meaning they weren't currently there.
Look at the explanation!!! Saxib I know everything about Khaawarij
Points from above hadith:
This man objected to the decision of prophet and showed his preference over the decision of prophet. He showed disrespect to the prophet. He rebelled against the Prophet (sallallaahualaihi wasallam) in the sense that accused him of treachery. ( He is counted amongst the Kafir and not as a companion( sahaba) of the prophet). He is
considered the first of the Kharij (the Seceders" or "the Rebels )to arise in Islam. The root of his sickness was that he preferred his own opinion above that of the Prophet . If he had waited to hear what the Prophet had to say, he would have realized that no opinion can be given precedence over that of The Prophet (s) .
He went against the Command of Allah subhanhu wa tala.
Say, (O Muhammad, to mankind): If ye love Allah, follow me; Allah will love you and forgive you your sins. Allah is Forgiving, Merciful. ( Quran , 3: 31)
