It was narrated from 'Aishah:

"A woman asked the Prophet ﷺ: 'O Messenger of Allah, how should I perform Ghusl when I become pure?' He said: 'Take a piece of cotton wool scented with musk and clean yourself with it.' She said: 'How should I clean myself with it?' He said: 'Clean yourself with it.' She said: "How should I clean myself with it?' The Messenger of Allah ﷺ said: 'Subhan Allah!' and turned away from her." 'Aishah understood what the Messenger of Allah ﷺ meant, and said: "So I pulled her toward me and told her what the Messenger of Allah ﷺ meant."

أَخْبَرَنَا الْحَسَنُ بْنُ مُحَمَّدٍ، قَالَ حَدَّثَنَا عَفَّانُ، قَالَ حَدَّثَنَا وُهَيْبٌ، قَالَ حَدَّثَنَا مَنْصُورُ بْنُ عَبْدِ الرَّحْمَنِ، عَنْ أُمِّهِ، صَفِيَّةَ بِنْتِ شَيْبَةَ عَنْ عَائِشَةَ، أَنَّ امْرَأَةً، سَأَلَتِ النَّبِيَّ ﷺ قَالَتْ يَا رَسُولَ اللَّهِ كَيْفَ أَغْتَسِلُ عِنْدَ الطُّهُورِ قَالَ " خُذِي فِرْصَةً مُمَسَّكَةً فَتَوَضَّئِي بِهَا " . قَالَتْ كَيْفَ أَتَوَضَّأُ بِهَا قَالَ " تَوَضَّئِي بِهَا " . قَالَتْ كَيْفَ أَتَوَضَّأُ بِهَا قَالَتْ ثُمَّ إِنَّ رَسُولَ اللَّهِ ﷺ سَبَّحَ وَأَعْرَضَ عَنْهَا فَفَطِنَتْ عَائِشَةُ لِمَا يُرِيدُ رَسُولُ اللَّهِ ﷺ قَالَتْ فَأَخَذْتُهَا وَجَبَذْتُهَا إِلَىَّ فَأَخْبَرْتُهَا بِمَا يُرِيدُ رَسُولُ اللَّهِ ﷺ .
