Is it permissible to seek divorce and go to one's family home when the husband forces his wife to engage in anal intercourse, justifying his act by claiming that the hadiths prohibiting it are unsound, while the wife fears that if she refuses, she will be cursed by the angels?

Anal intercourse is forbidden and a major sin. A wife is not permitted to obey her husband in this matter, because obedience is only due in what is good, and there is no obedience to a created being in disobedience to the Creator. If the husband forces his wife to do it, she is not at fault. However, she must advise him, explain the religious ruling to him, and prevent him from doing so, even if it leads to him seeking a divorce. Some scholars believe that a separation between the spouses is obligatory if they both agree to anal intercourse.
