حَدَّثَنَا أَبُو الْيَمَانِ أَخْبَرَنَا شُعَيْبٌ عَنْ الزُّهْرِيِّ قَالَ أَخْبَرَنِي عُرْوَةُ بْنُ الزُّبَيْرِ أَنَّ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ کَانَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَرَ بِصِيَامِ يَوْمِ عَاشُورَائَ فَلَمَّا فُرِضَ رَمَضَانُ کَانَ مَنْ شَائَ صَامَ وَمَنْ شَائَ أَفْطَرَ
