Keenness to be clean and smell good is one of the good manners and characteristics that the Muslim learns from his religion. This becomes more important when meeting people and sitting with them, especially in the case of Jumu‘ah and prayers in congregation. In this hadith, the Messenger of Allah (blessings and peace of Allah be upon him) enjoins doing ghusl on Fridays. So if the Muslim wants to go to the mosque to pray Jumu‘ah, he should do ghusl and wash his entire body, as he does in ghusl in the case of janabah. The purpose of this is to clean himself and to remove any unpleasant smells, lest he annoy or offend other attendees. This is part of the etiquette of attending the mosque and prayers in congregation. This is advice from the Prophet (blessings and peace of Allah be upon him) to do what is most appropriate and best on such occasions..
