What is the difference between describing something as disbelief, ruling that a specific person is a disbeliever, and believing that a specific person is a disbeliever?

Question:
May Allah reward you. Honorable Shaykh, a questioner asks: What is the difference between describing something as disbelief, ruling that a specific person is a disbeliever, and believing that a specific person is a disbeliever?

Answer:
As for ruling that actions are disbelief, such as supplicating to other than Allah, slaughtering for other than Allah, seeking aid from other than Allah, mocking the religion, or insulting the religion, this is disbelief by consensus, without doubt. However, the person who commits such an action must be examined. If he is ignorant, or if he is engaging in figurative interpretation, or if he is following a scholar without knowing his evidence, then the ruling of disbelief is withheld from him until the truth is made clear to him. If he has a doubtful matter, or if he is ignorant, or if there is a reason for him to rush in declaring him a disbeliever, then the evidence must be established against him.
The evidence is established against him. If the evidence is established against him and he persists in what he is doing, he is ruled to be a disbeliever, as he has no excuse. Yes.
