Is it permissible for a wife to seek divorce from her husband because he anally penetrated her, especially since this occurred only once and with her consent, and did not cause her physical harm?

Anal intercourse is forbidden, rather, it is a major sin, based on the Prophet's (peace and blessings be upon him) saying: "Accursed is he who has intercourse with a woman in her anus," and his (peace and blessings be upon him) saying: "Allah will not look at a man who has intercourse with a man or a woman in her anus." The wife has the right to seek divorce if the husband insists on doing it. And whoever repents, Allah will accept his repentance.
