**View**
      <div class="billing_tabs_text_part">
                <?php foreach($result as $row){?>
                  <p><?php echo $row['book_id']; }?></p>
                </div>

Solution

i am not sure which section is your problem so i suggest something how to find error

public function bill()
{
    echo 'ok'; // check controller work
    $id = $this->session->userdata('email');
    $this->load->database();
    echo 'ok1';
    $this->load->helper(array('form', 'url', 'html'));
    echo 'ok2';
    /*$this->load->model('fuser/Bill');
    $data['result'] = $this->Bill->bills();
    $this->load->view('user/messages', $data);*/
}

if this is print ok, ok1 , ok2 then this is query problem , if no print ok,ok1 then this is not query problem

in this case try to find error, if other ok then must print ok

public function bill()
{
    echo 'ok';
    /*$id = $this->session->userdata('email');
    $this->load->database();
    $this->load->helper(array('form', 'url', 'html'));
    $this->load->model('fuser/Bill');
    $data['result'] = $this->Bill->bills();
    $this->load->view('user/messages', $data);*/
}
