The ahl-ul-khibrah are those who can recognize the most knowledgeable by his writings, research and edicts. Those experts can be reached through communicating with the Howza. If such communication is not possible or determining the most knowledgeable is not possible, one is required to choose one of the scholars who have reached the level of ijtihad and fulfil the conditions of being a marja, and follow him. The chosen should be the most God-fearing amongst them if possible. Otherwise, the believer can choose one of them and follow his verdicts.
