Is there a difference between the scholars' saying: "This is an act of disbelief" and their saying: "This action is disbelief"?

Question:
He says: Honorable Shaykh, may Allah grant you success. Words such as "This is an act of disbelief" or "This action is disbelief" are heard on the tongues of scholars and jurists. Is there a difference between the word when it is definite or indefinite?

Answer:
The difference lies in the speech of the Messenger (peace and blessings be upon him), whereas the speech of scholars is not used as evidence. One only takes evidence from what has come in the Qur'an and the Sunnah. If disbelief is defined in the Qur'an or defined in the Sunnah, it is major shirk (associating partners with Allah). If it is negated or made indefinite, it is minor shirk. This is in the speech of Allah and the speech of His Messenger. As for the speech of scholars, if it agrees with what is in the Book of Allah and the Sunnah of His Messenger, it is truth; if it contradicts it, it is error. Yes.
