Sahih Muslim Book - 7, Hadith - 1958

حَدَّثَنِى هَارُونُ بْنُ سَعِيدٍ الأَيْلِىُّ وَأَحْمَدُ بْنُ عِيسَى قَالاَ حَدَّثَنَا ابْنُ وَهْبٍ أَخْبَرَنِى عَمْرٌو عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِى جَعْفَرٍ أَنَّ مُحَمَّدَ بْنَ جَعْفَرٍ حَدَّثَهُ عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ عَنْ عَائِشَةَ أَنَّهَا قَالَتْ كَانَ النَّاسُ يَنْتَابُونَ الْجُمُعَةَ مِنْ مَنَازِلِهِمْ مِنَ الْعَوَالِى فَيَأْتُونَ فِى الْعَبَاءِ وَيُصِيبُهُمُ الْغُبَارُ فَتَخْرُجُ مِنْهُمُ الرِّيحُ فَأَتَى رَسُولَ اللَّهِ -صلى الله عليه وسلم- إِنْسَانٌ مِنْهُمْ وَهُوَ عِنْدِى فَقَالَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- « لَوْ أَنَّكُمْ تَطَهَّرْتُمْ لِيَوْمِكُمْ هَذَا ».

It was narrated from 'Urwah bin Az-Zubair that 'Aishah said: "The people used to come to Jumu'ah from their houses and from Al-'Awali. They would come wearing cloaks that had gotten dusty, and they smelled. One of them came to the Messenger of Allah (s.a.w) while he was at my house, and the Messenger of Allah (s.a.w) said: 'You should clean yourselves for this day of yours."'
