Narrated `Aisha:
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 .
An Ansari woman asked the Prophet (ﷺ) how to take a bath after finishing from the menses. He replied, "Take a piece a 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.
