What is the ruling on ignoring the feeling that ritual impurity has not been removed after washing the site of urination three times? And what is the method for purifying a shoe from urine? And is it sufficient to pour water over an impure object if the impurity is not tangible? And what is the ruling on water that separates after washing a non-tangible or tangible impurity? And is it sufficient to pour water over the feet to purify them from water mixed with urine, or must they be rubbed?

Obsessive whispering (waswasah) is a serious disease, and its cure lies in completely ignoring it and not giving in to it. Washing and purifying the shoe is not necessary unless one has prayed with it. The feeling that impurity has not been removed after istinja' (washing after defecation/urination) is a waswasah, and it is sufficient to have a strong presumption that the impurity has been removed. Purifying a shoe contaminated with urine is done by removing the impurity itself by pouring water until it covers the affected area and its traces disappear. Non-visible impurity (najasah hukmiyah) is purified by running water over the contaminated spot. One should not doubt the type of impurity; if it has a taste, color, or smell, it is a visible impurity ('ayniyah), otherwise, it is a non-visible impurity (hukmiyah), and simply pouring water over it is sufficient. For water separated from an impurity, pouring water is sufficient for purification, and rubbing is not necessary if the impurity is removed without it.
