Is placing one's hand on the ground forbidden in Islamic law?

The answer can be summarized as follows: it is permissible, according to Islamic law, to take possession of and cultivate barren, unowned land, based on the Prophet's (peace be upon him) saying: "Whoever cultivates barren land that no Muslim has a right to, it becomes his," and "Whoever precedes others to something permissible has a greater right to it." However, if the land is owned by someone else, it is not permissible to utilize it without the owner's permission.
