If someone were to ask: How can you use these narrations as evidence when they state that the ghusl of Friday is obligatory, yet you consider it to be a recommended act and not a strict obligation? We respond: What these narrations imply by the term "obligatory" is that it is highly preferred and recommended for a person to perform it. Sometimes, an act is referred to as "obligatory" when it is highly recommended to do it, even if it is not a strict obligation that cannot be omitted under any circumstances. Evidence supporting this interpretation shows that the intent here is not an absolute obligation but rather a strong preference.
