Sahih al-Bukhari 315

Arabic

حَدَّثَنَا مُسْلِمٌ، قَالَ حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا مَنْصُورٌ، عَنْ أُمِّهِ، عَنْ عَائِشَةَ، أَنَّ امْرَأَةً، مِنَ الأَنْصَارِ قَالَتْ لِلنَّبِيِّ صلى الله عليه وسلم كَيْفَ أَغْتَسِلُ مِنَ الْمَحِيضِ قَالَ ‏"‏ خُذِي فِرْصَةً مُمَسَّكَةً، فَتَوَضَّئِي ثَلاَثًا ‏"‏‏.‏ ثُمَّ إِنَّ النَّبِيَّ صلى الله عليه وسلم اسْتَحْيَا فَأَعْرَضَ بِوَجْهِهِ أَوْ قَالَ ‏"‏ تَوَضَّئِي بِهَا ‏"‏ فَأَخَذْتُهَا فَجَذَبْتُهَا فَأَخْبَرْتُهَا بِمَا يُرِيدُ النَّبِيُّ صلى الله عليه وسلم‏.‏

English translation

Narrated `Aisha:An Ansari woman asked the Prophet (ﷺ) how to take a bath after finishing from the menses. He replied, "Take a piece of cloth perfumed with musk and clean the private parts with it thrice." The Prophet (ﷺ) felt shy and turned his face. So I pulled her to me and told her what the Prophet (ﷺ) meant
