Does the prayer become void if something that interrupts it passes from the middle of the place of prostration or its end, when there is a barrier that is not sufficient?

The woman, dog, and donkey do not invalidate the prayer. The "interruption" mentioned in the texts refers to a reduction in reward due to the heart being preoccupied by the passing of one of them. There is no difference whether they pass from the middle of the prostration area, or below it, or beyond it; none of that invalidates the prayer.
