The ruling on praying in a temporary prayer area on land whose owner is unknown

Question:
Honorable Shaykh, may Allah grant you success. A questioner says: The residents, or some of the residents, of a neighborhood in Riyadh built a temporary prayer area to pray in on land that is owned, but they do not know its owner, and without permission from the mosque administration. These people ask: What is the ruling on our prayer in this temporary area, given that there are nearby mosques, but they are farther away than this temporary one?

Answer:
There is nothing wrong with that. The default is permissibility, praise be to Allah. It is lenient in this matter, and the default is permissibility, as long as they do not know that the owner has not given permission. Yes.
