حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا لَيْثٌ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ، وَعَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ، أَنَّ عَائِشَةَ ـ رضى الله عنها ـ زَوْجَ النَّبِيِّ صلى الله عليه وسلم قَالَتْ وَإِنْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم لَيُدْخِلُ عَلَىَّ رَأْسَهُ وَهْوَ فِي الْمَسْجِدِ فَأُرَجِّلُهُ، وَكَانَ لاَ يَدْخُلُ الْبَيْتَ إِلاَّ لِحَاجَةٍ، إِذَا كَانَ مُعْتَكِفًا
