Is the one who denies something known from the religion by necessity declared a disbeliever in his own right?

Question:
May Allah reward you, Your Eminence the Shaykh. The questioner says: If someone denies something known from the religion by necessity, does anyone have the right to declare him a disbeliever, or is this specific to scholars and people of knowledge?

Answer:
If he is ignorant and does not know the well-known matters of the religion, it is explained to him and clarified for him. If he persists after having knowledge and clarification, then he is ruled to be an apostate. However, this is undertaken by the scholars who are firmly grounded in knowledge. Not everyone undertakes declaring someone a disbeliever or ruling on apostasy; not everyone undertakes this. Yes.
