حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ عَمْرِو بْنِ دِينَارٍ، وَعُبَيْدِ اللَّهِ بْنِ أَبِي يَزِيدَ، قَالاَ لَمْ يَكُنْ عَلَى عَهْدِ النَّبِيِّ صلى الله عليه وسلم حَوْلَ الْبَيْتِ حَائِطٌ، كَانُوا يُصَلُّونَ حَوْلَ الْبَيْتِ، حَتَّى كَانَ عُمَرُ، فَبَنَى حَوْلَهُ حَائِطًا ـ قَالَ عُبَيْدُ اللَّهِ ـ جَدْرُهُ قَصِيرٌ، فَبَنَاهُ ابْنُ الزُّبَيْرِ.
