باب اسْتِحْبَابِ اسْتِعْمَالِ الْمُغْتَسِلَةِ مِنَ الْحَيْضِ فِرْصَةً مِنْ مِسْكٍ فِي مَوْضِعِ الدَّمِ ‏
Sahih Muslim 332 c

'A'isha reported:

Asma (daughter of Shakal) asked the Messenger of Allah (ﷺ) about washing after menstruation. He said: Everyone amongst you should use water (mixed with the leaves of) the lote-tree and cleanse herself well, and then pour water on her head and rub it vigorously till it reaches the roots of the hair. Then she should pour water on it. Afterwards she should take a piece of cotton smeared with musk and cleanse herself with it. Asma' said: How should she cleanse herself with the help of that? Upon this he (the Messenger of Allah) observed: Praise be to Allah, she should cleanse herself. 'A'isha said in a subdued tone that she should apply it to the trace of blood. She (Asma) then further asked about bathing after sexual intercourse. He (the Holy Prophet) said: She should take water and cleanse herself well or complete the ablution and then (pour water) on her head and rub it till it reaches the roots of the hair (of her) head and then pour water on her. 'A'isha said: How good are the women of Ansar (helpers) that their shyness does not prevent them from learning religion.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالَ ابْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ إِبْرَاهِيمَ بْنِ الْمُهَاجِرِ، قَالَ سَمِعْتُ صَفِيَّةَ، تُحَدِّثُ عَنْ عَائِشَةَ، أَنَّ أَسْمَاءَ، سَأَلَتِ النَّبِيَّ صلى الله عليه وسلم عَنْ غُسْلِ الْمَحِيضِ فَقَالَ ‏"‏ تَأْخُذُ إِحْدَاكُنَّ مَاءَهَا وَسِدْرَتَهَا فَتَطَهَّرُ فَتُحْسِنُ الطُّهُورَ ثُمَّ تَصُبُّ عَلَى رَأْسِهَا فَتَدْلُكُهُ دَلْكًا شَدِيدًا حَتَّى تَبْلُغَ شُئُونَ رَأْسِهَا ثُمَّ تَصُبُّ عَلَيْهَا الْمَاءَ ‏.‏ ثُمَّ تَأْخُذُ فِرْصَةً مُمَسَّكَةً فَتَطَهَّرُ بِهَا ‏"‏ ‏.‏ فَقَالَتْ أَسْمَاءُ وَكَيْفَ تَطَهَّرُ بِهَا فَقَالَ ‏"‏ سُبْحَانَ اللَّهِ تَطَهَّرِينَ بِهَا ‏"‏ ‏.‏ فَقَالَتْ عَائِشَةُ كَأَنَّهَا تُخْفِي ذَلِكَ تَتَبَّعِينَ أَثَرَ الدَّمِ ‏.‏ وَسَأَلَتْهُ عَنْ غُسْلِ الْجَنَابَةِ فَقَالَ ‏"‏ تَأْخُذُ مَاءً فَتَطَهَّرُ فَتُحْسِنُ الطُّهُورَ - أَوْ تُبْلِغُ الطُّهُورَ - ثُمَّ تَصُبُّ عَلَى رَأْسِهَا فَتَدْلُكُهُ حَتَّى تَبْلُغَ شُئُونَ رَأْسِهَا ثُمَّ تُفِيضُ عَلَيْهَا الْمَاءَ ‏"‏ ‏.‏ فَقَالَتْ عَائِشَةُ نِعْمَ النِّسَاءُ نِسَاءُ الأَنْصَارِ لَمْ يَكُنْ يَمْنَعُهُنَّ الْحَيَاءُ أَنْ يَتَفَقَّهْنَ فِي الدِّينِ ‏.‏
