What is the cure for the obsessive whispers (waswas) that afflict a girl in her purity and acts of worship, affecting her psyche and health?

We advise you to seek treatment for obsessive-compulsive disorder by completely ignoring it, busying yourself with memorizing the Qur’an, seeking knowledge, performing Ruqya (Islamic exorcism/healing), diligently reciting adhkar (remembrances of Allah), and having a good opinion of Allah. For Istinja’ (cleaning after relieving oneself), it is sufficient to clean the outlet, and there is no need for exaggeration. Avoid staying long in the bathroom. Worship is built upon ease, so do not exaggerate in Istibra’ (ensuring no drops of urine remain). If you feel wetness after Istinja’, consider it from the water you sprinkled, and do not pay attention to doubts, for certainty is not removed by doubt.
