What is the ruling on a husband having anal sex with his wife? If the husband and wife did that several times, would the woman be considered divorced? If both of them repented, what would be the ruling then? May Allah reward you!

*A: Having sexual intercourse with wife in her anus is one of the great deadly sins, as it contradicts Allah's saying: “Your wives are a tilth for you, so go to your tilth, when or how you will.” The place of tilth is the front private part. The Prophet (صلى الله عليه وسلم) said: “He who has sexual intercourse with his wife through her anus is accursed.” Yet, anyone who repents, Allah will accept his repentance. By doing this act, a woman is not divorced but the husband and the wife have to sincerely repent. Allah (سبحانه وتعالى) says: “And all of you beg Allah to forgive you all, O believers, that you may be successful.” The Prophet (صلى الله عليه وسلم) said: “Repentance wipes out all the previous misdeeds.” The Prophet (صلى الله عليه وسلم) said: “He who repents from his sins is like the one who did not commit a sin.”* May Allah grant us success!
