Is performing an act one swore to abandon, but in a place other than that intended by the oath, considered a breaking of the oath?

If you were not administered an oath, then you do not break it except by doing what you intended to avoid when you took the oath, because oaths are based on intention. Ibn Qudamah said: "The basis of an oath is the intention of the one who takes it. So, if he intends something with his oath that the words can bear, then it reverts to that intention, whether what he intended is in accordance with the apparent meaning of the لفظ (wording) or contrary to it." However, if an oath was administered to you concerning a matter related to the rights of another, then the issue has a detailed explanation.
