Does the divorce of a person suffering from obsessive-compulsive disorder (waswas) take effect if he utters it, and what is the ruling on a husband taking back his wife after a previous fatwa stated that the divorce did not take effect, and is it considered a divorce if the words of divorce are uttered unintentionally due to waswas?

Divorce does not occur through whispers (waswas) and doubts, nor through the wife's returning to her husband after a mufti (definition)'s fatwa (definition) that divorce has occurred. Live with your wife honorably, and do not hesitate to enjoy her. You must completely disregard these whispers and beware of getting carried away by them.
