حَدَّثَنَا مُحَمَّدُ بْنُ عِيسَى، وَقُتَيْبَةُ بْنُ سَعِيدٍ، قَالاَ حَدَّثَنَا يَزِيدُ، عَنْ خَالِدٍ، عَنْ عِكْرِمَةَ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتِ اعْتَكَفَتْ مَعَ النَّبِيِّ صلى الله عليه وسلم امْرَأَةٌ مِنْ أَزْوَاجِهِ فَكَانَتْ تَرَى الصُّفْرَةَ وَالْحُمْرَةَ فَرُبَّمَا وَضَعْنَا الطَّسْتَ تَحْتَهَا وَهِيَ تُصَلِّي .
