The Criterion for Describing a Person as One of the Khawarij

Question:
Who says that a person is not described as one of the Khawarij unless the attribute of declaring others disbelievers (takfir) is found in him, is this statement correct?

Answer:
The doctrine of the Khawarij has types. Some of it is by belief alone, even if one does not speak it; if one believes in the doctrine of the Khawarij and holds it to be correct, he is a Khariji, even if he does not speak it. Likewise, the doctrine of the Khawarij is by speech: speech and incitement to rebel against the rulers, and speech in declaring sinful Muslims disbelievers—those who are safe from shirk (associating partners with Allah) and kufr (disbelief)—declaring them disbelievers for their sins, even if they do not carry weapons. This is part of the doctrine of the Khawarij; he is called a Khariji by his doctrine. Likewise, if he carries weapons against the Muslims, this is more severe. So rebellion has types. Yes.
