Shaikh Saaleh Al-Fawzaan [may Allaah preserve him] said:

None violates the honour of the scholars who are upon the truth, except one of three [people]: Either a hypocrite known for [his] hypocrisy, or an evil sinner who hates the scholars because they prevent him from his sinful [acts] of disobedience, or a misguided hizbi who hates the scholars because they neither agree with his hizbiyyah nor with his deviated views.
