Are there conditions and impediments that must be met before we rule that a person is an innovator, just as is the case with declaring someone a disbeliever?

Question:
He says: Honorable Shaykh, may Allah grant you success, are there conditions that must be present and impediments that must be absent before we rule that a person is [an innovator], just as is the case with declaring someone a disbeliever, or do we rule that he is an innovator directly?

Answer:
My brothers, ruling with takfir (declaring someone a disbeliever), labeling someone as an innovator, and labeling someone as an open sinner—this is not permissible to spread among students and people, and among beginners. This is the concern of the scholars. It is the scholars who rule on these matters regarding those to whom they apply and who see the benefit in applying them.
As for beginners and students, they should focus on seeking knowledge, focus on seeking knowledge, and leave these issues alone, because they enter into them out of ignorance. They may accuse an innocent person, and they may vouch for a guilty person, because they have no knowledge and no understanding. So they should devote themselves to seeking knowledge and leave takfir (declaring someone a disbeliever), labeling someone as an open sinner, and labeling someone as an innovator to the people of knowledge. Yes.
