The ruling on a resident taking advantage of the dispensations for travel for a need he knows will keep him there for more than four days

Question:
He says: Honorable Shaykh, may Allah grant you success. A person traveled to a town at the distance that permits shortening the prayer and stayed there for a need, not knowing when his need would end, and he would return once it was finished. However, he knows that he will stay for more than four days. Is he permitted to take advantage of the dispensations for travel, even if the period is long?

Answer:
No. He knows that he will stay for more than four days because his need will not end within four days. Therefore, he becomes a resident, and it is not permissible for him to take advantage of the dispensations for travel, because he knows that his need will not end within four days.
