What is the way to get rid of the satanic whispers that cause repeated ghusl and doubt about impurity, which negatively affect prayer and daily life?

The suffering from obsessive-compulsive disorder (OCD) related to ritual purity (tahara) has a simple solution that requires determination and patience. The treatment involves several matters: consistent remembrance of Allah (dhikr), seeking His help for healing, and completely ignoring the whispers of Satan. If you relieve yourself and perform istinja' (washing after defecation/urination), do not pay attention to doubts about your hand becoming impure or water splashing, because the default state is purity, and "certainty is not removed by doubt." Achieving cleanliness (inqaa') is by washing the private parts, and be certain that you are pure and your prayer is valid. Acting upon this advice and persevering in it will, by the grace and power of Allah, remove the OCD. It is also recommended to consult a specialized doctor, knowing that healing may require long-term determination and patience because improvement comes gradually. Consider your struggle as fulfilling the verse: "O you who have believed, persevere and endure and remain stationed and fear Allah that you may succeed."
