What should a wife do if her husband has anal intercourse with her and abandons her if she does not obey him, and she fears God and wishes to repent, knowing that only unlawful acts arouse him, and she cannot seek a divorce due to her circumstances and children?

It is not permissible to engage in anal intercourse with one's wife, and it is not permissible for the wife to obey her husband in this matter. The wife must repent and not return to such an act. It is not permissible for the husband to deprive her of lawful sexual intercourse because she refused to obey him in something forbidden. She should advise him kindly, and if he does not desist, she should threaten to inform someone who can restrain him. Otherwise, she should seek a divorce. As for the children, the mother has the right to their custody, and if he refrains from spending on them, she should take the matter to the Sharia court.
