'Aishah reported:

Asma' entered upon the Messenger of Allah ﷺ and said: Messenger of Allah, how should one of us take bath when she is purified from her menses ? He said: She should take water mixed with the leaves of lote-tree; then should perform ablution and wash her head and rub it so much so that water reaches the roots of the hair; she should then our water upon her body. Then she should take a piece of cloth (or cotton or wool) and purify with it. She asked: Messenger of Allah, how should I purify with it ? 'Aishah said: I understood what he (the Prophet) said metaphorically. I, therefore, said to her: Remove the marks of blood.

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، أَخْبَرَنَا سَلاَّمُ بْنُ سُلَيْمٍ، عَنْ إِبْرَاهِيمَ بْنِ مُهَاجِرٍ، عَنْ صَفِيَّةَ بِنْتِ شَيْبَةَ، عَنْ عَائِشَةَ، قَالَتْ دَخَلَتْ أَسْمَاءُ عَلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ كَيْفَ تَغْتَسِلُ إِحْدَانَا إِذَا طَهُرَتْ مِنَ الْمَحِيضِ قَالَ
" تَأْخُذُ سِدْرَهَا وَمَاءَهَا فَتَوَضَّأُ ثُمَّ تَغْسِلُ رَأْسَهَا وَتَدْلُكُهُ حَتَّى يَبْلُغَ الْمَاءُ أُصُولَ شَعْرِهَا ثُمَّ تُفِيضُ عَلَى جَسَدِهَا ثُمَّ تَأْخُذُ فِرْصَتَهَا فَتَطَّهَّرُ بِهَا " . قَالَتْ يَا رَسُولَ اللَّهِ كَيْفَ أَتَطَهَّرُ بِهَا قَالَتْ عَائِشَةُ فَعَرَفْتُ الَّذِي يَكْنِي عَنْهُ رَسُولُ اللَّهِ ﷺ فَقُلْتُ لَهَا تَتَّبِعِينَ بِهَا آثَارَ الدَّمِ .
