Is it permissible for a traveler to shorten the prayer for six months, five days a week, returning to his city on the weekly holiday?

If the distance between two cities is 80 kilometers or more, you may shorten the prayer during your travel, both going and returning. If you intend to reside in the city you reached for more than four days, then you must perform the full prayer from the moment of your arrival. However, if you reside in a place without specifying a definite duration for the completion of your need, then you remain in the status of shortening the prayer, even if your stay is prolonged, because you are considered a traveler.
