Showing records/data from another database table based on the id in laravel

Hello Please I am trying to view the records of a user based on the user id I used as a foreign key in another table in laravel. Basically I want the name of the userID to show.

This is my Controller

    public function index()
    {
       
        
        $id = User::all();
        $organisedTrips = organisedTrip::where('userID', '=', $id)->get();
    
        $organisedTrips = organisedTrip::paginate(4);
        return view('welcome', compact('organisedTrips'));
        
    }
