حَدَّثَنَا الْحَسَنُ بْنُ مُحَمَّدِ بْنِ الصَّبَّاحِ، حَدَّثَنَا عَفَّانُ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ خَالِدٍ الْحَذَّاءِ، عَنْ عِكْرِمَةَ، قَالَ قَالَتْ عَائِشَةُاعْتَكَفَتْ مَعَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ امْرَأَةٌ مِنْ نِسَائِهِ فَكَانَتْ تَرَى الْحُمْرَةَ وَالصُّفْرَةَ فَرُبَّمَا وَضَعَتْ تَحْتَهَا الطَّسْتَ ‏.‏
