Purification (Kitab Al-Taharah)
A Woman Washes Her Garment That She Wears During Her Menses [To Pray In]
حَدَّثَنَا النُّفَيْلِيُّ، حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ أَبِي نَجِيحٍ، عَنْ عَطَاءٍ، عَنْ عَائِشَةَ، قَالَتْ قَدْ كَانَ يَكُونُ لإِحْدَانَا الدِّرْعُ فِيهِ تَحِيضُ وَفِيهِ تُصِيبُهَا الْجَنَابَةُ ثُمَّ تَرَى فِيهِ قَطْرَةً مِنْ دَمٍ فَتَقْصَعُهُ بِرِيقِهَا .
'Aishah said: One of us would have a shirt in which she would menstruate and in it she became sexually defiled. Then if she ever saw any drop of blood in it, she would rub it off by applying her saliva.
