Does standing up from waiting for prayer out of necessity affect her reward?

Question:
A woman sits waiting for the next prayer time to begin, reciting tasbih, tahlil, and praying as Allah wills for her. Does her reward decrease if she stands up from her place due to a circumstance, such as opening the door or answering the telephone, or the like?

Answer:
It does not harm her, if Allah wills. If she stands up out of necessity, it does not harm her, if Allah wills. She opens the door for someone knocking, or answers the telephone; it does not harm her, if Allah wills. She is in a state of great good. Yes.
