Purification (Kitab Al-Taharah)
A Woman Washes Her Garment That She Wears During Her Menses [To Pray In]
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ الْعَبْدِيُّ، أَخْبَرَنَا إِبْرَاهِيمُ بْنُ نَافِعٍ، قَالَ سَمِعْتُ الْحَسَنَ، - يَعْنِي ابْنَ مُسْلِمٍ - يَذْكُرُ عَنْ مُجَاهِدٍ، قَالَ قَالَتْ عَائِشَةُ مَا كَانَ لإِحْدَانَا إِلاَّ ثَوْبٌ وَاحِدٌ تَحِيضُ فِيهِ فَإِنْ أَصَابَهُ شَىْءٌ مِنْ دَمٍ بَلَّتْهُ بِرِيقِهَا ثُمَّ قَصَعَتْهُ بِرِيقِهَا .
'Aishah said: Each of us (wives of the Prophet) had only one clothe in which she would menstruate. Whenever it was smeared with blood, she would moisten it with her saliva and scratch it with saliva.
