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 ‏.‏
