in short, the gist of akhbārī ideology is that nothing but the aḥadīth of the infallible can serve as authoritative evidence in islam. akhbārīs also differ from usūlīs in their rejection of the "guardianship of the islamic jurists", arguing that preachers of religion have no role in politics, clerics should advise political leaders but not govern themselves. akhbaris believe in separation of religion and state in absence of twelfth imam, they say that only an infallible ruling imam has a right to combine religion and state; and which will be accomplished only after the arrival of awaited shia imam.
