It is narrated from Hazrat Aisha (may Allah be pleased with her) that sometimes the Prophet (peace and blessings be upon him) would be praying at home and the door would be closed. When I would come, the Prophet (peace and blessings be upon him) would walk over, open the door for me, and then return to his place and stand there. Hazrat Aisha (may Allah be pleased with her) also mentioned that the door was towards the Qiblah.
