"Take a piece of cloth perfumed with musk and purify yourself with it." She said: "How should I purify myself with it?" He covered his face then said: "Subhan Allah! Purify yourself with it." 'Aishah said: "I took the woman aside and said: 'Wipe away the traces of blood with it.'" (Using translation from Nasāʾī 251)  

أَنَّ امْرَأَةً سَأَلْتِ النَّبِيَّ ﷺ عَنْ غُسْلِهَا مِنَ الْمَحِيضِ؟ فَأَخْبَرَهَا كَيْفَ تَغْتَسِلُ ثُمَّ قَالَ «خُذِي فِرْصَةً مِنْ مِسْكٍ فَتَطَهَّرِي بِهَا» قَالَتْ وَكَيْفَ أَتَطَهَّرُ بِهَا؟ فَاسْتَتَرَ كَذَا ثُمَّ قَالَ «سُبْحَانَ اللهِ تَطَهَّرِي بِهَا» قَالَتْ عَائِشَةُ فَجَذَبْتُ الْمَرْأَةَ وَقُلَتُ تَتَّبِعِينَ بِهَا أَثَرَ الدَّمِ
