What is the ruling on the divorce of a person suffering from obsessive-compulsive disorder (waswas) who experiences recurring thoughts and obsessions about divorce, and does his divorce take effect despite it being merely self-talk (hadith nafs)?

You are suffering from obsessive thoughts. Do not pay attention to these devilish thoughts of divorce, for Satan wants to make your life miserable and corrupt your religion. The devil's plot is weak, and you possess the most powerful weapon: the remembrance of Allah. Seek refuge in Allah, increase your remembrance of Him, and steadfastly perform acts of obedience. We advise you not to consult various muftis regarding these obsessive thoughts; instead, completely disregard them.
