Muhammad ibn Hilal reported that he saw the rooms of the wives of the Prophet, may Allah bless him and grant him peace. The rooms were made of palm trunks covered with hair. The transmitter (Muhammad ibn Abi Fudayk) said, "I asked him about 'A'isha's room and he said, 'Its door faced Syria.' I asked, 'Was it one or two spans?' 'Its door was one span,' he replied. I asked, 'And what was it made of?' He said, 'From cypress or teak wood.'"

حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ، قَالَ: حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي فُدَيْكٍ، عَنْ مُحَمَّدِ بْنِ هِلاَلٍ، أَنَّهُ رَأَى حُجَرَ أَزْوَاجِ النَّبِيِّ صلى الله عليه وسلم مِنْ جَرِيدٍ مَسْتُورَةً بِمُسُوحِ الشَّعْرِ، فَسَأَلْتُهُ عَنْ بَيْتِ عَائِشَةَ، فَقَالَ: كَانَ بَابُهُ مِنْ وِجْهَةِ الشَّامِ، فَقُلْتُ: مِصْرَاعًا كَانَ أَوْ مِصْرَاعَيْنِ؟ قَالَ: كَانَ بَابًا وَاحِدًا، قُلْتُ: مِنْ أَيِّ شَيْءٍ كَانَ؟ قَالَ: مِنْ عَرْعَرٍ أَوْ سَاجٍ.
