Does the divorce of a man who suffers from a heavy head, rapid tension and anger, frequent forgetfulness, and doubts about purity and prayer, while maintaining remembrance of Allah, take effect? And what do you advise for him: ruqyah or a visit to the doctor?

It is likely that this person is afflicted with obsessive-compulsive disorder (OCD). Treatment involves seeking Allah's help, frequent remembrance of Him (dhikr), ignoring the obsessive thoughts, and consistently performing legal ruqyah. If these methods are not effective, the matter should be presented to a Muslim psychiatrist.

As for the divorce of this person, it does not take effect if it was uttered under the influence of obsessions, as stated by Ash-Shafi'i: "And whoever has his intellect overcome, either by a natural predisposition or a sudden illness that he did not bring upon himself through disobedience, is not bound by divorce, nor prayer, nor penalties. This applies to the imbecile, the insane, the obsessive, the delirious, and everyone afflicted with an illness that overcomes their intellect, as long as their intellect is overcome."

Ibn Rushd said: "The obsessive person is not bound by divorce, and there is no divorce in such a case, because that is from Satan, so one should be distracted from it and not pay attention to it."

However, if the obsessions are separate from the divorce, or if the divorce was uttered while he was sane and intended it, then his divorce takes effect, even if he is obsessive, based on Ash-Shafi'i's statement: "If his intellect returns to him and he divorces in that state or commits a punishable offense, the penalty is applied to him, and the religious obligations become binding upon him."
