What is the ruling on obsessive thoughts of shirk (polytheism) or kufr (disbelief) concerning Allah, and is seeking refuge in Allah from them sufficient?

Such whispers do no harm as long as they are resisted and disliked, and they are a clear sign of faith. The treatment involves seeking refuge in Allah through supplication, seeking protection from Satan, frequently reciting the Qur'an and devotional remembrances (dhikr), contemplating Allah's creations, and turning away from these thoughts and not dwelling on them. Indeed, scholars have agreed that this is one of the most important means of treatment. The case can also be presented to mental health specialists.
