Question:
If I am alone in the house and someone knocks on the door, is it permissible for me to interrupt my prayer and open the door?
Answer:
No, it is not permissible for you to interrupt your prayer, but you should make a sound of clearing your throat so that the one seeking permission knows that you are in prayer, as the Prophet (peace and blessings be upon him) used to do when 'Ali (may Allah be pleased with him) sought permission to enter while he was praying; he would make a sound of clearing his throat so that 'Ali would know he was praying and would wait.
