(37) باب السَّرِيرِ
Narrated `Aisha:
Allah's Messenger (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.
