حَدَّثَنَا أَبُو الْيَمَانِ، قَالَ أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي عُرْوَةُ، أَنَّ عَائِشَةَ، قَالَتْ لَقَدْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي الْفَجْرَ، فَيَشْهَدُ مَعَهُ نِسَاءٌ مِنَ الْمُؤْمِنَاتِ مُتَلَفِّعَاتٍ فِي مُرُوطِهِنَّ ثُمَّ يَرْجِعْنَ إِلَى بُيُوتِهِنَّ مَا يَعْرِفُهُنَّ أَحَدٌ.
