[Machine] When this verse was revealed, the Messenger of Allah ﷺ sent a message to Uwaim bin Sa'idah and said, "What is this purification that Allah has praised you for?" He replied, "O Messenger of Allah, no man or woman among us goes to the bathroom without washing their backside, or he said, their private parts." The Prophet ﷺ said, "This is the practice of Hudaifah bin Al-Yaman as narrated from him, and it is also the Sunnah (tradition) of Aisha, may Allah be pleased with her, that a woman washes her private parts before intercourse."
لَمَّا نَزَلَتْ هَذِهِ الْآيَةُ بَعَثَ رَسُولُ اللهِ ﷺ إِلَى عُوَيْمِ بْنِ سَاعِدَةَ فَقَالَ مَا هَذَا الطُّهُورُ الَّذِي أَثْنَى الله عَلَيْكُمْ بِهِ فَقَالَ يَا رَسُولَ اللهِ مَا خَرَجَ مِنَّا رَجُلٌ وَلَا امْرَأَةٌ مِنَ الْغَائِطِ إِلَّا غَسَلَ دُبُرَهُ أَوْ قَالَ مَقْعَدَهُ فَقَالَ النَّبِيُّ ﷺ فَفِي هَذَا وَرُوِيِّنَا عَنْ حُذَيْفَةَ بْنِ الْيَمَانِ أَنَّهُ كَانَ يَسْتَنْجِي بِالْمَاءِ إِذَا بَالَ وَعَنْ عَائِشَةَ ؓ مِنَ السُّنَّةِ غَسْلُ الْمَرْأَةِ قُبُلَهَا
