What the rule says, and what it does not ask of you

You made wudu. You know you made it, because you remember doing it. Then a doubt arrives saying that maybe it broke. In the law, the wudu is knowledge and the doubt is not, so the wudu stands.

That is the ruling. It is worth knowing, because a great many people carry this for years without ever being told it, and being told it is a relief.

Now the honest part. Knowing the ruling and being able to act on it are two different things, and this course is not going to pretend otherwise. Working directly against a compulsion, staying in the discomfort while not doing the thing that settles it, is the treatment. It works. It is also careful, graded work that people do alongside a therapist, and it goes wrong when it is attempted from a page. So we are telling you what the law says. We are not handing you an exercise.
