Akhbari

[3] Akhbari also do not follow/imitate (taqleed) the teaching of a mujtahid, specifically a marja‘ (model for imitation) who practice a modern form of ijtihad (independent legal reasoning).

Interpretation of the Quran, and complete in-depth gnostic knowledge (al-rāsikhūn fi al-ʿilm Arabic: الراسخون فی العلم) of revelation from the Imams is also passed down.

As of the twenty-first century, Akhbari form a tiny minority within Shia Islam, with Usulis making up the mainstream majority.

Akhbarism started as a movement with the writings of Muhammad Amin al-Astarabadi (d. 1627) and achieved its greatest influence in the late Safavid (1501–1736) and early post-Safavid era.

Therefore, even for new events occurring during the Major Occultation, Akhbaris continue to follow the traditions of Ahlul Bayt, as per the saying of Imam Muhammad al-Mahdi where he said "As for the new events, which will occur (during my occultation) turn to the narrators of our traditions, because they are my proof to you, while I am the proof of Allah to them"[8] Akhbari reject fatāwa based on ijtihad, they also reject the permissibility of writing exegesis of the Qur'an without quoting the narrations of the infallible Ahlu l-Bayt.

[14][15] Akhbaris contend that, over the course of the history of Twelver Shi'ism since the Occultation, Usuli ulama have progressively usurped more and more of the functions of the Hidden Imam.

Muhaqqiq al-Karkhi (About 300 years after the second transgression) was the first to suggest, arguing from the hadith of ‘Umar ibn Hanzala, that the ulama were the Nā'ib al-'Amm (general representative) of the Hidden Imām.

[16] Although the aforementioned scholars were not mujtahids in their full capacity, they introduced innovative concepts into Shī‘a theology which later formed the basis of the exegetical school.

The revival of Akhbārism, or "neo-Akhbārism" as it became known, was under the dean of Karbala scholarship, Yusuf Al Bahrani (1695–1772), who led an intellectual assault on Usuli thought in the mid-18th century.

An Akhbari critique of Usulism had emerged in Bahrain at the beginning of the 18th century, partly spurred by the weaknesses of the Usuli sponsoring the Safavid empire.

[17] By succeeding to the role of dean of Karbala as one of the pre-eminent scholars of the age, al-Bahrani's extended this Bahrain-based debate to the rest of the Shī‘a world.

He did not, however, go so far as to say that no verse in the Qur'an could be understood without the interpretation of the Imams, a position held by the Safavid-era Akhbari Astarabadi which Shaykh Yusuf denounced as extremist.

Although this controversy had begun as a minor disagreement on a few points, it eventually grew into a bitter, vituperative dispute culminating in Behbahani's declaration that the Akhbaris were infidels (Kuffar).

During the first Russo-Persian War (1804–1813), Fath Ali Shah's son and heir, Abbas Mirza, who was conducting the campaign, turned to the new ulama and obtained from Shaykh Ja'far Kashif al-Ghita' and other eminent clerics in Najaf and Isfahan a declaration of jihad against the Russians, thus implicitly recognizing their authority to issue such a declaration – one of the functions of the Hidden Imām.

[6] Usuli clerical power reached its natural conclusion with control and domination of the state as promulgated through Vilayat al-Faqih under the authority of the Supreme Leader.

They practice this based on the last letter Imām Mahdi wrote to ‘Alī ibn Muhammad, fourth trusted follower of the Lesser Occultation.

[20] Akhbaris claim that only the Imāms may be described as āyat Allahs (Ayatollahs, "signs of God") based on the Hadith-e-Tariq,[21] and that no one else has the right to ascribe this divinely appointed title to themselves.
