Narrated `A'isha:
The Prophet (ﷺ) used to offer his night prayer while I was sleeping across in his bed. Whenever he intended to offer the witr prayer, he used to wake me up and I would offer the witr prayer too.
حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا هِشَامٌ، قَالَ حَدَّثَنِي أَبِي، عَنْ عَائِشَةَ، قَالَتْ كَانَ النَّبِيُّ صلى الله عليه وسلم يُصَلِّي، وَأَنَا رَاقِدَةٌ مُعْتَرِضَةً عَلَى فِرَاشِهِ، فَإِذَا أَرَادَ أَنْ يُوتِرَ أَيْقَظَنِي فَأَوْتَرْتُ.
