ذِكْرُ الْبَيَانِ بِأَنَّ قَوْلَ عَائِشَةَ فَقِيلَ لَهُمْ: لَوِ اغْتَسَلْتُمْ أَرَادَتْ أَنَّ النَّبِيَّ ﷺ أَمَرَهُمْ بِذَلِكَ
The people came for Jumu'a prayer from their houses in the neighbouring villages dressed in woollen garments on which dust was settled and this emitted a foul smell. A person among them (those who were dressed so) came to the Messenger of Allah ﷺ while he was in my house. The Messenger of Allah (may peace he upon him) said to him: Were you to cleanse yourselves on this day. (Using translation from Muslim 847a)
أَنَّهَا قَالَتْ كَانَ النَّاسُ يَنْتَابُونَ الْجُمُعَةَ مِنْ مَنَازِلِهِمْ مِنَ الْعَوَالِي فَيَأْتُونَ فِي الْعَبَاءِ وَيُصِيبُهُمُ الْغُبَارُ وَالْعَرَقُ فَيَخْرُجُ مِنْهُمُ الرِّيحُ فَأَتَى رَسُولَ اللَّهِ ﷺ إِنْسَانٌ مِنْهُمْ وَهُوَ عِنْدِي فَقَالَ رَسُولُ اللَّهِ ﷺ «لَوْ أَنَّكُمْ تَطَهَّرْتُمْ لِيَوْمِكُمْ هَذَا»
