What is the ruling on doubting the completion of prostration after rising from it? And should prostration only be repeated, or the entire prayer? And what is the ruling on erring in the Tashahhud by saying the word "wa rahmatullahi," and should the "wa" be repeated with it, and is it considered an invalidating addition? And does the prayer become invalidated by the intention to repeat Al-Fatiha as a precaution, even though it was recited correctly? And what should one do if they err in the second part of the final Tashahhud, or repeat something they did not err in during the first Tashahhud? And how should one deal with excessive doubt and forgetfulness in prayer to the extent of repeating pillars and feeling dizzy?
Do not doubt that this is a significant whisper (waswasa), and its cure is to disregard it. Most scholars hold the view that prostrating on limbs other than the face is recommended, not obligatory. Therefore, whoever does not place their feet during prostration, their prayer is valid according to most scholars, and the person afflicted by waswasa may adopt the lightest of opinions. If you doubt your recitation or tashahhud, do not pay attention to the doubt. However, if you are absolutely certain that you mispronounced a letter, then you are only required to repeat the word in which you erred. A person afflicted by waswasa should not issue fatwas for themselves, but rather follow the scholar who has given them a fatwa.
