Is it permissible for a wife to abandon and refuse her husband's invitation to bed if he practices sex excessively and in a physically harmful way to her, and forces her to watch and participate with him in masturbation?

A wife must obey her husband if he calls her to bed, and she is not permitted to refuse except for an excuse such as illness, menstruation, an obligatory fast, or harm. If a man has intercourse frequently, the spouses should agree on a suitable amount for their situation. If they dispute, the ruler should impose a decision. If you are harmed by your husband's intercourse, you are not obligated to respond and you do not sin by refusing. As for masturbation, it is forbidden, and obedience is not permissible in it, but each spouse is permitted to masturbate with the hand of the other.
