how to dispaly index method in Laravel 5.2

I am going to view My users table data (username,email) in index.blade.php file. I have UsersController.php like this

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use Auth;
use App\User;

use App\Http\Requests;

class UserController extends Controller
{
    public function index()
{
     $users = User::userr()->get();

    return view('users.index')->withUser($users);
}

}

My User Model is

<?php

namespace App;
use Auth;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'username', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];





public function getAvatarUrl()
{
        return "http://ift.tt/ww139j" . md5(strtolower(trim($this->email))) . "?d=mm&s=40";
}

public function scopeUserr($query)
{
     return $query->where('username',Auth::user()->id);

}

}

and index.blade.php is

@if(isset($user))
@foreach($user as $use)
<h1>{ !! $use->username !! }</h1>
@endforeach
@endif

@endsection

routes is

Route::get('/index', function(){
    return view('users.index');
});

but when I visit index view is it display empty page (no error) and did not show name and email

how can fix this prob?
