What is the ruling on a husband having anal intercourse with his wife when he is unable to stop himself from doing so due to psychological disturbances, and what are the implications for a husband who cannot control his actions during intercourse?

Engaging in anal intercourse with one's wife is forbidden by religious law (shar'an) and naturally repulsive (ṭabʿan). The one who commits this act is exposed to Allah's curse and expulsion from His mercy, as the Messenger of Allah, peace and blessings be upon him, said: "Cursed is he who has intercourse with his wife in her anus." Furthermore, the perpetrator suffers psychological and physical harm, and it can cause separation between spouses if they both agree to it. It is obligatory to abstain from what Allah has forbidden and to seek permissible alternatives.
