Prayers (Salat)
Chapter: Whoever says "Nothing annuls As-Salat (the prayer) (i.e. nothing of what others do, not the praying person himself)."
Narrated `Aisha:
(the wife of the Prophet) Allah's Messenger (ﷺ) used to get up at night and pray while I used to lie across between him and the Qibla on his family's bed.
