Sahih al-Bukhari · Book 14: Witr Prayer · The Prophet (pbuh) used to wake his family up for the Witr prayer
Narrated `A'isha:
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.
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.
