Narrated `Aisha:
حَدَّثَنَا يَحْيَى ، قَالَ حَدَّثَنَا ابْنُ عُيَيْنَةَ ، عَنْ مَنْصُورِ ابْنِ صَفِيَّةَ ، عَنْ أُمِّهِ ، عَنْ عَائِشَةَ ، أَنَّ امْرَأَةً، سَأَلَتِ النَّبِيَّ صلى الله عليه وسلم عَنْ غُسْلِهَا مِنَ الْمَحِيضِ، فَأَمَرَهَا كَيْفَ تَغْتَسِلُ قَالَ " خُذِي فِرْصَةً مِنْ مِسْكٍ فَتَطَهَّرِي بِهَا ". قَالَتْ كَيْفَ أَتَطَهَّرُ قَالَ " تَطَهَّرِي بِهَا ". قَالَتْ كَيْفَ قَالَ " سُبْحَانَ اللَّهِ تَطَهَّرِي ". فَاجْتَبَذْتُهَا إِلَىَّ فَقُلْتُ تَتَبَّعِي بِهَا أَثَرَ الدَّمِ.
A woman asked the Prophet (ﷺ) about the bath which is taken after finishing from the menses. The Prophet (ﷺ) told her what to do and said, "Purify yourself with a piece of cloth scented with musk." The woman asked, "How shall I purify myself with it" He said, "Subhan Allah! Purify yourself (with it)." I pulled her to myself and said, "Rub the place soiled with blood with it."
