How can a person afflicted with obsessive-compulsive disorder (OCD) – which results in thoughts and actions perceived as kufr (disbelief) – escape Hellfire, given their feeling that their repentance might not be accepted based on the verse from Surah Al Imran?

We ask Allah to grant you well-being and to remove these whisperings from you, for a Muslim does not become an infidel merely by them. Turn away from these whisperings and do not pay attention to them. Increase your supplications and be diligent in performing the prescribed remembrances (adhkar), while also seeking treatment from a specialized doctor. We also advise you to marry, for in it there is tranquility for the soul and protection for one's chastity.
