Sahih al-Bukhari · Book 8: Prayers (Salat) · To offer As-Salat (the prayers) on the bed
Narrated `Urwa:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ ، قَالَ حَدَّثَنَا اللَّيْثُ ، عَنْ يَزِيدَ ، عَنْ عِرَاكٍ ، عَنْ عُرْوَةَ ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ يُصَلِّي وَعَائِشَةُ مُعْتَرِضَةٌ بَيْنَهُ وَبَيْنَ الْقِبْلَةِ عَلَى الْفِرَاشِ الَّذِي يَنَامَانِ عَلَيْهِ.
The Prophet (ﷺ) prayed while `Aisha was lying between him and his Qibla on the bed on which they used to sleep.
