What is the ruling on one who opposes the Salaf in a matter of the matters of faith?

Question:
Honorable Shaykh, may Allah grant you success. One who opposes the Salaf in a matter of the matters of faith, such as the matters of the Murji'ah and others, does he become one who opposes the methodology of the Salaf and is no longer one of them?

Answer:
Yes. If he opposes them in the matters of faith, it is obligatory to follow the Salaf in the matters of faith. If he opposes them regarding the Murji'ah, or opposes them regarding the compulsion of the Khawarij, or opposes them regarding the doctrine of the Mu'tazilah, then he is not one of them, he is not of the Salaf. Yes, he becomes one of those who claimed affiliation to it. If he claimed affiliation to the doctrine of the Khawarij, he is a Khariji. If he claimed affiliation to the doctrine of the Mu'tazilah, he is a Mu'tazili. If he claimed affiliation to the doctrine of the Murji'ah, he is a Murji'i. Yes.
