How can one get rid of the feeling of urine drops coming out after ablution, and what is the method for dealing with the obsessive whispers (waswas) of impurities that affect the cleanliness of the home and belongings, and how is impurity judged, its essence identified, and its transmission determined? And does touching dry or wet impurity invalidate ablution, and what is meant by "pardoning minor impurities," and does an abundance of impurity invalidate ablution or prayer, and what does the phrase "قطع الشك باليقين" (cut off doubt with certainty) mean?

Dismiss the whispers and pay them no mind, for the feeling of urine drops exiting should not be heeded unless you are absolutely certain of their exit, a certainty you could swear upon. The fundamental principle regarding things is purity. Therefore, do not deem something impure except with absolute certainty. If you doubt the transference of impurity, the default is that it has not transferred. If you touch something impure while you are in a state of ablution (wudu'), your purity is not invalidated. The meaning of dispelling doubt with certainty is to abandon what is doubtful and adhere to what is certain. So, if you doubt the exit of impurity or the contamination of a place, the default is its absence until certainty to the contrary is achieved.
