Akhbaris argue that throughout the history of Twelver Shi'ism since the Occultation, Usuli
ulama have gradually assumed functions that originally belonged to the Hidden Imam. They maintain that this process occurred in five distinct stages, each representing a further transgression or expansion of authority.
First transgression As early as the 5th century AH / 11th century CE—more than 150 years after the Occultation of the 12th Imām—Shaykhu t-Ta'ifa reinterpreted the doctrine to allow the delegation of the Imām's judicial authority to scholars trained in
fiqh. In his writings, however, he stresses that this responsibility should be assumed by the
ʿulamāʾ only when no other qualified individual is available. Shaykhu t-Ta'ifa also considered the
ʿulamāʾ to be the most suitable figures to distribute religious taxes, given their knowledge of the rightful recipients. Nevertheless, he maintained that individuals were still permitted to distribute such taxes on their own if they wished. He likewise permitted
fuqahāʾ to organize the Friday prayer in the absence of the Imām or his specific representative. Prominent Shīʿa scholars who rejected this interpretation include: • ʿAlam al-Huda (a member of Shaykhu t-Ta'ifa's scholarly circle) • Ibn Idris •
Allamah al-Hilli This development effectively exceeded the limits set by Shaykhu t-Ta'ifa two centuries earlier, marking what Akhbaris consider the first major transgression.
Third transgression Muhaqqiq al-Karkhi—writing roughly 300 years after the second transgression—was the first to argue, based on the hadith of ‘Umar ibn Hanzala, that the
ulama served as the ''Nā'ib al-'Amm'' (general representatives) of the Hidden Imām. However, he limited the practical application of this idea to one specific area: assuming the responsibility of leading the Friday prayer. By assuming leadership of the Karbala scholarly community as one of the foremost thinkers of his time, al-Bahrani expanded this Bahrain-centered debate across the wider Shī‘a world.
Ayatollah Behbahani Under al-Bahrani, Usuli scholarship was regarded as impure, although al-Bahrani himself did not possess significant political influence. It was
Muhammad Baqir ibn Muhammad Akmal al-Wahid Behbahani who decisively challenged the Akhbaris and eventually emerged as the most politically influential cleric in Karbala by 1772. Behbahani’s theology was strongly opposed by the Akhbaris, and what began as a minor doctrinal disagreement escalated into a fierce and hostile dispute, culminating in Behbahani declaring the Akhbaris to be
infidels (
kuffār). This followed the pattern of other transgressions by overthrowing the limits of its prior (fourth) transgression.
Iranian Revolution Following the
Iranian Revolution, the Usuli school gained increasing popularity within communities that had previously adhered to Akhbarism. The consolidation of Usuli clerical authority reached its fullest expression in the doctrine of
Vilayat al-Faqih, through which the
Supreme Leader exercises overarching religious and political authority. == Rejection of the Mujtahids ==
