Mukhtasar Bukhari (Abridged) 252 — Praying on beds is permissible

Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) says that the Messenger of Allah (peace and blessings be upon him) used to pray on his bedding at home, and she (i.e., Aisha, may Allah be pleased with her) would be lying on the bedding between him (peace be upon him) and the place of prostration, in the manner of a bier.
