Bishr ibn al-Mufaddal narrated to us, Bard narrated to us, from al-Zuhri, from Urwah, from Aisha, who said: "The Prophet, peace and blessings of Allah be upon him, used to pray in the house while the door was closed upon him. I came, and he walked until he opened it for me, then he returned to his place." And she described that the door was in the direction of the Qibla.
