Brief Explanation
Benefits: … Its explanation is as follows: if a person cultivates land that is not owned by anyone, it becomes his property. Now, if another person comes and plants a tree in that land in order to take possession of it, then the Prophet sallallahu alayhi wa sallam states that this person is an oppressor and a root of injustice, and he has no right whatsoever.
