أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ يَزِيدَ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي يَعْفُورٍ، عَنْ مُسْلِمٍ، عَنْ مَسْرُوقٍ، قَالَ قَالَتْ عَائِشَةُ رضى الله عنها كَانَ إِذَا دَخَلَتِ الْعَشْرُ أَحْيَا رَسُولُ اللَّهِ صلى الله عليه وسلم اللَّيْلَ وَأَيْقَظَ أَهْلَهُ وَشَدَّ الْمِئْزَرَ ‏.‏
