Brief Explanation
Benefits: … In any case, urinating in the bathhouse is prohibited. There can be various reasons for this, for example: the place becoming impure, foul odor emanating from there, the arising of doubts (waswasah) because of it, and natural disposition (fitrah) strongly disliking this act.
