I didn’t use to have doubts about if I washed after emptying my bowels. After I read Sistanis law: person doubts whether or not he has purified the anus or urinary outlet, it is necessary that he purifies it even if he habitually purifies it immediately after emptying his bowels and/or bladder.

I am now having doubts, even though I know I washed my private parts after emptying my bowels. What should I do?

Do not care about the doubts.
