"The Messenger of Allah ﷺused to pray at night while I was lying down sleeping between him and the Qibla on his bed. When he wanted to pray witr he would wake me up and I would pray witr" (Using translation from Nasāʾī 759)
كَانَ رَسُولُ اللهِ ﷺ يُصَلِّي بِاللَّيْلِ وَأَنَا مُعْتَرِضَةٌ بَيْنَهُ وَبَيْنَ الْقِبْلَةِ فَإِذَا أَرَادَ أَنْ يُوتِرَ أَيْقَظَنِي فَأَوْتَرْتُ
