What is the validity of the claim of one who claims to be on the methodology of the people of the Sunnah and the community, but encourages rebellion against the rulers?

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: If there is a person who says that he is from the people of the Sunnah and the community, and that he is on the methodology of the Salaf, but he contradicts the methodology of the people of the Sunnah in one of its foundations, such as rebelling against the rulers, or calling for rebellion against them,

Answer:
He is not from the people of the Sunnah. This is from the Khawarij. He is not from the people of the Sunnah. The one who incites to fitnah (trial, discord or temptation) and to breaking the bond of obedience is a Khariji from the Khawarij. This is the methodology of the Khawarij.
