The Pillars of the Khawarij School of Thought

Question:
Is there anyone in this age who carries the arrogance of the Khawarij?

Answer:
Glory be to Allah, that is what is found among the Khawarij. Declaring Muslims to be disbelievers is the school of the Khawarij, and even worse than that is killing Muslims and attacking them; this is the school of the Khawarij. Rising up against the one in authority—three things, three things. First, declaring Muslims to be disbelievers; this is from the school of the Khawarij. Second, rebelling against the obedience of the one in authority; this is from the school of the Khawarij. Third, making the blood of Muslims lawful; this is from the school of the Khawarij. These are the schools of the Khawarij. Even if a person believes in his heart but does not speak and does not do anything, if he believes in his heart in the validity of the school of the Khawarij, he becomes a Khariji; he becomes one of the Khawarij by his belief and his opinion, which he has not severed. Yes.
