What is the ruling on divorcing a wife who physically and verbally abuses her daughter and does not respond to her husband's request to change her behavior?

Striking children for disciplinary purposes has legal Islamic controls, and insulting children has a worse effect than striking them, increasing their stubbornness. Advise your wife kindly and remind her of the prohibition against anger if she is quick to anger. Divorce is not a solution because it scatters the family and causes the daughter to be lost. Direct your daughter, if she is discerning, to behave well and not provoke her mother, and explain to her the mother's high status.
