Messenger of Allah ﷺ used to offer his prayer (while standing) in the midst of the bed, and I used to lie in front of him between him and the Qibla It I had any necessity for getting up and I used to dislike to get up and face him (while he was in prayer), but I would gradually slip away from the bed.  

كَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّي وَسْطَ السَّرِيرِ وَأَنَا مُضْطَجِعَةٌ بَيْنَهُ وَبَيْنَ الْقِبْلَةِ تَكُونُ لِيَ الْحَاجَةُ فَأَكْرَهُ أَنْ أَقُومَ فَأَسْتَقْبِلَهُ فَأَنْسَلُّ انْسِلاَلاً
