What is the ruling on a wife insulting and cursing her husband when they disagree? Is it permissible to hit her after advising her? What should the husband do to rectify her behavior? Is divorce the solution in this situation?

A wife's transgression against her husband is a reprehensible act and a sin; she is considered disobedient (nashiz). It is permissible to strike a disobedient wife a non-painful blow if admonition and shunning are ineffective, and divorce is the last resort. You are not obligated to divorce your wife; you can be patient with her and try to reform her through supplication, by saying: "O Allah, I ask You for her goodness and the goodness of what You have instilled in her, and I seek refuge in You from her evil and the evil of what You have instilled in her." Furthermore, mutual respect should prevail between spouses, and each should overlook the other's slip-ups.
