Question:
May Allah reward you. In his other question, he says: One time I entered a mosque to perform the midday prayer shortened, as I was traveling, and I found a congregation praying. I caught one rak'ah with them. What must I do? Do I make up three rak'ahs, or do I add one rak'ah, because I was shortening my prayer?
Answer:
If the congregation you joined with are shortening the prayer, then you shorten it. You add one rak'ah to the one you caught with them and conclude the prayer. However, if they are completing the prayer, it is obligatory for you to complete it by praying four rak'ahs. Yes, because the one praying behind the imam follows his imam.
