Is the odor that the questioner smells in her undergarments, after forgetting to dry herself, the smell of urine, noting that it differs from the smell of her adolescent brother’s urine, who suffers from enuresis, and that she changes her undergarments multiple times a day and finds the same odor most of the time?

We advise you to turn away from these whisperings (waswas (definition)) and to pay no attention to them. The basic principle is that you are pure and that no urine has exited from you. Therefore, do not judge that anything has exited unless you attain certain conviction. As long as you are not certain that the smell is that of urine, the basic principle is purity. Know that if you were to die in this state, there would be nothing against you.
