If one stays to fulfill a need and does not intend to settle, does he shorten the prayer?

Question : Or if he stays to fulfill a need without the intention of settling.

Answer : He shortens the prayer indefinitely, if he stays to fulfill a need and does not intend to settle. That is, he does not intend an indefinite stay, nor is a stay without a limit necessary. He may have intended to stay to fulfill a need, but he does not know when it will end, and he does not intend an indefinite stay. In that case, he shortens the prayer indefinitely. What does "indefinitely" mean? It means that even if he remained for his entire life, he would shorten the prayer.
