حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ، وَأَبُو أُسَامَةَ عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ إِنْ كُنَّا آلَ مُحَمَّدٍ ـ صلى الله عليه وسلم ـ لَنَمْكُثُ شَهْرًا مَا نُوقِدُ فِيهِ بِنَارٍ مَا هُوَ إِلاَّ التَّمْرُ وَالْمَاءُ . إِلاَّ أَنَّ ابْنَ نُمَيْرٍ قَالَ نَلْبَثُ شَهْرًا .
