Sunan Ibn Majah 942 
It was narrated that ‘Aishah said:
“The Messenger of Allah had a reed mat that he would spread out during the day, and make into a compartment at night, towards which he would perform prayer.”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عُمَرَ، حَدَّثَنِي سَعِيدُ بْنُ أَبِي سَعِيدٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ لِرَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ حَصِيرٌ يُبْسَطُ بِالنَّهَارِ وَيَحْتَجِرُهُ بِاللَّيْلِ يُصَلِّي إِلَيْهِ ‏.‏
