People used to come to the Friday prayer from their homes in the outlying areas, traveling through the dust, so dust and sweat would cling to them and perspiration would pour from them. One such person came to the Messenger of Allah ﷺ while he was with me, and the Prophet ﷺ said, "If only you would purify yourselves for this day of yours."
كان الناس ينتابون يوم الجمعة من منازلهم، العوالي، فيأتون في الغبار، يصيبهم الغبار والعرق، فيخرج منهم العرق، فأتى رسول الله ﷺ إنسان منهم وهو عندي، فقال النبي ﷺ: لو أنكم تطهرتم ليومكم هذا.
Bukhari narrated it in the Book of Friday Prayer (902), and this is his wording, and Muslim narrated it in the Book of Friday Prayer (847), both through Ubaydullah bin Abu Jafar, that Muhammad bin Jafar bin Zubayr told him, from Urwa bin Zubayr, from Ayesha, the wife of the Prophet ﷺ, and she related it.In Muslim's version, "so they would come in coarse wool garments." Hafiz said in Fath al-Bari, "This is more accurate." In another version reported by Muslim, Ayesha said, "The people used to do their own work, and they had no servants, so they would have an unpleasant smell about them. It was said to them, 'If only you would bathe on Friday.'"In a version reported by Bukhari (903), "The people used to do their own manual labor, and when they went out to the Friday prayer, they would go in their working condition, so it was said to them, 'If only you would bathe.'"His saying, "kufaah" is the plural of kaaf, like qudaah is the plural of qaadi, meaning the servants who would take care of the work for them. And "tafl" means an unpleasant odor.
