The ruling on repeating a prayer due to doubt about its validity
Machine translationRead the Arabic original
Question:
The questioner says: Shaykh Abu 'Abdullah, I am troubled by doubts that some of my previous prayers were flawed, and perhaps they were not accepted. So I repeat the prayers many times. Is this repetition valid?
Answer:
No, this repetition is not valid, and this is waswas (whispers of Satan). If you have prayed, then your prayer is sufficient, if Allah wills, and you do not repeat it unless it becomes clear that you prayed in an incorrect manner, such as praying without ritual purity or neglecting one of its pillars. As long as you have prayed and finished the prayer, do not pay attention to the waswas; doubt after the act of worship does not affect it. Yes.
