The characteristics of the Khawarij and the ruling on one who calls to their ideology

Question:
This questioner says to you both: What is the legal ruling that can be applied to the misguided sect? Is this sect considered among the Khawarij? And is it called upon?

Answer:
I mean, did our first speech all go, erased by the night or the day? Yes, whoever calls to the ideology of the Khawarij, stands for it, and executes it, is among the Khawarij. The Khawarij are characterized by, and their methodology is summarized in, three issues. The first issue is declaring Muslims to be disbelievers for major sins that are less than shirk (associating partners with Allah); this is the doctrine of the Khawarij. The second matter is rebelling against the rulers, the rulers of the Muslims, by breaking the bond of obedience. The third matter among the characteristics of the Khawarij is that they consider the blood of Muslims to be lawful, as the Messenger (peace and blessings be upon him) said: These are the characteristics of the Khawarij.
