Does a movable anal skin tag, contaminated with a small amount of faeces, invalidate ablution, especially with the severe discomfort felt during movement or prayer, and can one adopt the Maliki school of thought that it does not invalidate ablution because it is not a customary occurrence?

There is no harm for one afflicted with waswasa (obsessive doubts) in adopting the easier opinion, which is the Maliki madhhab (school of thought) stating that an unusual discharge—such as the exit of worms or stones from either of the two private parts, or something that is not a discharge, like gurgling, or if its exit is due to an illness like incontinence (salas)—does not nullify ablution.
