How can one get rid of the intense fear of making mistakes in acts of worship, which prevents tasting the sweetness of faith and devotion?

The fear mentioned has become pathological and may lead to obsessive thoughts (waswasah). Therefore, matters should be dealt with naturally, without exaggeration or extremism in prayer and ablution. The fear of Allah should be strengthened by contemplating His names and attributes and the horrors of the Hereafter, which motivates one to avoid sins and perform duties with moderation, far from exaggeration and obsessive thoughts. Seek help through supplication (du'a) and the pursuit of beneficial knowledge to distinguish between healthy and pathological fear.
