What is the ruling on repeatedly performing ablution and prayer multiple times due to doubt about passing wind or dripping, and what is the remedy for the evil whispers that compel a person to harm themselves and isolate themselves from people?

We advise you to consult doctors and strive to repel these whispers (waswas), by performing wudu and prayer once without repeating them, and by not isolating yourself from people. What you fear is merely a whisper (waswasa) that has no reality, and there is no sin upon you for it as long as you do not act upon it or speak of it. Live your life normally while supplicating that Allah may avert these whispers from you.
