Young men asked the farm guard for permission to use it, and he granted it, saying that the owner of the farm does not object. What is the ruling?

The questioner : Noble Shaykh, what is your opinion regarding young men who went to the farm and rented it from the guard so that they could eat there and use the facilities, such as the swimming pool and electricity, among other things?
And when they asked the guard about the ruling of the farm owner, he said: He does not object to that?

The Shaykh : Well, what appears is that the guard is trustworthy, and if he tells people: Enter and enjoy the shade and the blessing, there is no harm. Yes.
