Is there sin upon one who objected to religious subject matter and disliked the Houris due to intrusive thoughts during prayer and ablution, and then regretted that?

We ask Allah to grant you a speedy recovery, and you must be patient and have a good opinion of Allah. Obsessive-compulsive disorder is an illness, and its cure is available by theign of Allah. As for being discontent with religion and its rulings, such as objecting to prayer or the houris, this is a departure from religion. Whoever experiences this must repent to Allah and return to Islam by uttering the two testimonies of faith.
