All sufis – all of the ten great religious orders- have pledged allegiance to the Mahdi (pbuh). Consequently it is not possible for Hazrat Mahdi (pbuh) to be subject to any sheikh. All sheikhs have become subjects to Hazrat Mahdi (pbuh) whether they like it or not. At that moment all inspiration is distributed to the whole through Mahdi (pbuh). - Harun Yahya
