أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ سُفْيَانَ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ أُمَيَّةَ، عَنْ عَبْدِ اللَّهِ بْنِ عُرْوَةَ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ تَزَوَّجَنِي رَسُولُ اللَّهِ صلى الله عليه وسلم فِي شَوَّالٍ وَأُدْخِلْتُ عَلَيْهِ فِي شَوَّالٍ وَكَانَتْ عَائِشَةُ تُحِبُّ أَنْ تُدْخِلَ نِسَاءَهَا فِي شَوَّالٍ فَأَىُّ نِسَائِهِ كَانَتْ أَحْظَى عِنْدَهُ مِنِّي
