(Taqlid). Following authority. Man should only ever follow Allah's Authority. The Verifiers, who are the highest category of the friends of Allah, have verified the knowledge gained through following Allah's Authority.
(Tahqiq). The perfect knowers of Allah, who are the Verifiers and the People of Blame, have verified the knowledge which they have received through following the authority (taqlid) of the Sacred Law. Therefore tahqiq completes and perfects taqlid.
