Question:
The questioner says: If I am traveling and I want to shorten the afternoon prayer after I have prayed the midday prayer with the imam in congregation, but there is a congregation praying and I do not know whether they are travelers or residents, what should I do?
Answer:
Join them. If they conclude the prayer, you shorten it with them. If they complete it, you complete it with them. Your ruling is their ruling: if they shorten, you shorten with them; if they complete, you complete with them. Yes.
