The ruling on opening the door during prayer

Question : A man knocked on the door. The door was close, so he moved forward, but he was facing the qiblah; or he moved backward, and he was facing the qiblah; or he went to the right, and he was facing the qiblah; or to the left, and he was facing the qiblah. Then he opened the door.

Answer : This is a minor matter. If the door is close, it is a minor matter, because the Messenger (peace and blessings be upon him) opened the door for 'Aishah. That is fine.
