Is it permissible to divorce a wife who is an innovator (Mubtadi'ah) and does not love the Companions and the Mother of theievers?

Divorce is permissible if there is a reason for it. It is permissible to divorce a wife who insults the Companions, and it may even be recommended or obligatory. If the matter does not reach the level of declaring the Companions disbelievers, or insulting or cursing them, then divorcing her is recommended. However, if she declares the Companions disbelievers, especially the Mother of Believers Aisha, then separating from her and annulling her marriage is obligatory.
