Friday is the best of days; it is the weekly festival (eid) of the Muslims, on which they gather to remember Allah (dhikr). Hence there are several points of etiquette to be observed on Fridays. In this hadith, the Prophet (blessings and peace of Allah be upon him) explains some of them. He (blessings and peace of Allah be upon him) explains that doing ghusl on Friday is obligatory for every adult, in the sense that it is so important for every adult male who is required to attend Jumu‘ah that it is almost like an obligatory duty for him. Another of these sunnahs is brushing the teeth and cleaning them with a siwak or by other means, scrubbing the teeth with something that will clean them. Another of these sunnahs is putting on perfume that has a good smell. Doing ghusl and cleaning the mouth are part of the etiquette of attending the mosques and prayers in congregation. It is advice from the Prophet (blessings and peace of Allah be upon him) to do that which is appropriate on such occasions. The ‘Amr referred to here is ‘Amr ibn Sulaym, the narrator of the report. The words “As for brushing the teeth and putting on perfume…”, which appear towards the end of the report, indicate that the conjunction does not mean that these actions are all at the same level of importance. It is as if he was certain that ghusl only is obligatory, because this is clearly stated in the hadith; he did not say anything about the other actions, because of the possibility that they may or may not be obligatory. It was also said that as the Prophet (blessings and peace of Allah be upon him) mentioned together doing ghusl and putting on perfume on Friday, and everyone agrees that there is no blame on the one who does not put on perfume on Friday, if he has no offensive odours that could annoy or offend other people in the mosque, the same applies to the one who does not do ghusl, because the reason for both is the same. The same applies to brushing the teeth..
