Have occasional waswas but a brother has poor recitation of Fatiha should I pray behind him? Repeat? What should I do if I find out during the prayer, leave and pray on my own? Eg adds kha to alhamdulilah, says “dwaleen” instead of “dhaleen. Mosque imam picked up on these mistakes during halaqas

Doubts that come from waswas are not acted upon.
