The Mihna: Inquisition on the Quran's Nature

# Al-Mihna: The Inquisition Over the Quran's Nature

The Theological Question at the Heart of the Crisis

In 218 AH / 833 CE, the Abbasid Caliph al-Ma'mun issued a decree from his military headquarters in Tarsus that would unleash the most severe theological crisis in early Islamic history. He ordered that all Islamic judges and senior scholars in Baghdad be summoned before the governor Ishaq ibn Ibrahim and tested on their belief regarding the nature of the Quran. Those who affirmed that the Quran was "created" (makhluq) — the position al-Ma'mun had formally adopted as state doctrine — would be approved to continue their posts. Those who refused or hesitated would be removed, imprisoned, or worse.

This was al-Mihna: the Trial, or the Ordeal. It would continue under three successive Caliphs for fifteen years, from 218 to 234 AH, and it would produce one of the most consequential episodes of religious resistance in Islamic history — centered on a scholar from Baghdad named Ahmad ibn Hanbal, who endured imprisonment and flogging rather than affirm something he believed was without Quranic or prophetic basis.

To understand the Mihna, one must first understand the theological stakes. The Mu'tazilite school of rational theology (kalam) had developed a comprehensive rational theology that placed great emphasis on the absolute unity and transcendence of Allah. One of their central claims was that the Quran — the speech of Allah — must be "created" rather than eternal, because if the Quran were uncreated and eternal, this would imply the existence of something eternal alongside Allah, which they argued constituted a form of shirk (associating partners with Allah). Their slogan was: "there is no eternal thing except Allah alone."

The Sunni scholarly tradition responded with a distinction. The Quran as Allah's Speech (kalam) is an attribute of Allah, and Allah's attributes are not separate beings alongside Him. To say that Allah's Speech is eternal is not to posit a second eternal being but to affirm an eternal attribute of the One God — just as we affirm that Allah's knowledge is eternal without thereby positing two eternal beings. The ink, paper, and human recitation of the Quran are created things; but the Quran as divine Speech, as the meaning and content revealed to the Prophet ﷺ, is uncreated.

The Origins: Al-Ma'mun's Adoption of Mu'tazilism

Al-Ma'mun (r. 198-218 AH) was intellectually the most sophisticated of the Abbasid Caliphs, a patron of the House of Wisdom and deeply engaged with theological and philosophical questions. His adoption of the Mu'tazilite position appears to have been genuine rather than purely political, but it was also connected to political considerations: the Mu'tazilite theology gave the Caliph a role as the supreme arbiter of theological questions in a way that the hadith-based scholarly tradition did not. If reason, guided by the Caliph, could adjudicate theological disputes, then the independent authority of the hadith scholars was subordinate to caliphal authority.

Al-Ma'mun had previously attempted to name the Shia Imam Ali al-Ridha as his successor — a remarkably heterodox political move that had alarmed the Sunni scholarly establishment. His later decision to impose the "created Quran" doctrine through state coercion was another assertion of caliphal authority over the domain that the hadith scholars had come to regard as their own.

In his initial letter to the Baghdad governor in 218 AH, al-Ma'mun wrote: "Allah has made the Commander of the Faithful responsible for the protection of religion... The ignorant have invented what the ancients did not hold, claiming that the Quran is uncreated... This is a clear form of shirk." He ordered that scholars be examined and that those who refused the correct answer (that the Quran is created) be punished.

The Testing of the Scholars: Compliance and Resistance

The Baghdad scholars were summoned before the governor Ishaq ibn Ibrahim, and the majority — under combination of fear, pragmatic calculation, and genuine uncertainty about whether resistance was worth its costs — affirmed the Mu'tazilite position. Classical accounts preserve the names of scholars who complied, and later Sunni tradition did not uniformly condemn them, recognizing that some may have been under genuine duress and interpreted their compliance as a case of necessity (darura).

Among those who refused outright, the most prominent was Ahmad ibn Hanbal (164-241 AH), who along with Muhammad ibn Nuh al-Jarrah initially refused to comply. Both were put in chains and transported toward the Caliph's headquarters in Tarsus. Muhammad ibn Nuh died on the journey. Ahmad ibn Hanbal survived to face interrogation.

Ahmad's response to the examination has been preserved in multiple accounts, most detailed in his own subsequent narrations and in the biographical literature of later centuries. His position was simple and immovable: "Show me evidence from the Quran or from the Sunnah of the Prophet ﷺ." The interrogators could produce no Quranic verse or authentic hadith that stated the Quran was created. Ahmad refused to affirm something for which he found no evidence in the primary sources, regardless of the political consequences.

Ahmad ibn Hanbal's Ordeal Under Three Caliphs

Al-Ma'mun died before Ahmad reached Tarsus (218 AH), and the new Caliph al-Mu'tasim (r. 218-227 AH) continued the Mihna. Ahmad was brought before al-Mu'tasim in Baghdad and subjected to a series of interrogation sessions attended by Mu'tazilite theologians who argued with him at length. The sessions were not purely theatrical — genuine debate took place, with the Mu'tazilites presenting their rational arguments and Ahmad responding with hadith-based counter-arguments.

The most powerful account of Ahmad's interrogation is preserved in the Manaqib Ahmad of Ibn al-Jawzi and in Ibn Kathir's al-Bidaya wa-l-Nihaya. When one interrogator pressed him to affirm the Mu'tazilite position, Ahmad reportedly said: "Bring me something from the Book of Allah or the Sunnah of the Prophet ﷺ." The interrogator offered philosophical arguments. Ahmad replied: "I do not know about your philosophy. I know only what the Prophet ﷺ said and what his Companions understood."

Al-Mu'tasim ordered Ahmad to be flogged. The flogging was severe — accounts describe him being struck between eighty and several hundred times on different occasions, falling unconscious, and being revived. Yet he did not recant. His famous response when sympathizers suggested he concede to avoid further suffering: "If the scholars give in under coercion and the common people do not know the correct position, when will the truth be clarified?" He understood that his resistance was not merely personal integrity but an act of communal service — the defense of a position the community needed to have maintained.

Ahmad's response to al-Mu'tasim personally demonstrated his careful distinction between the theological question and personal animosity. When asked how he viewed the Caliph, he said: "He is the Commander of the Faithful; I pray for him, I advise him sincerely, but I cannot affirm in religion what has no basis." This separation of political legitimacy from theological error was a sophisticated position: the Caliph was the legitimate ruler and deserved loyalty in his worldly capacity, but that loyalty did not extend to affirming false doctrine.

The Mihna continued under the third Caliph, al-Wathiq (r. 227-232 AH), who reportedly ordered that anyone who claimed the Quran was uncreated be executed. Ahmad ibn Hanbal spent most of this period in house arrest, prohibited from teaching but surviving. The pressure never broke him.

The End of the Mihna: Al-Mutawakkil's Reversal

The political and theological tide turned with the accession of al-Mutawakkil (r. 232-247 AH / 847-861 CE). Al-Mutawakkil had no sympathy for the Mu'tazilite theology and understood that the scholarly establishment's resistance to the Mihna had, over fifteen years, created enormous popular opposition to caliphal imposition of doctrine. In 234 AH / 848 CE, he formally ended the Mihna, declared the Mu'tazilite position abandoned as state doctrine, and ordered that scholars be freed and the Sunni position restored.

He also ordered — in a move that marked a decisive swing of the pendulum — that Mu'tazilite teachings be banned from public discourse, and he patronized leading Sunni scholars including Ahmad ibn Hanbal, who emerged from the Mihna as perhaps the most celebrated living scholar in the Islamic world. Al-Mutawakkil's support of Sunnism extended to measures against Shia practices and the destruction of the shrine over the grave of Husayn ibn Ali at Karbala — actions that went well beyond what Sunni scholarship endorsed and for which he bears responsibility.

The Legacy: Scholarship, Authority, and the Limits of Political Power

The Mihna's ending established several principles that would shape Sunni political and theological thought for centuries.

First, political power cannot override scholarly consensus on matters of aqeedah. The Caliph possesses legitimate authority in governance, military affairs, and administration of the law, but the content of Islamic belief is determined by the Quran, the Sunnah, and the consensus of the qualified scholars — not by caliphal decree. This principle was tested severely by the Mihna and emerged intact.

Second, the hadith-based scholarly tradition vindicated itself against rationalist theology in this confrontation. Ahmad ibn Hanbal's methodological insistence — "bring me evidence from Quran and Sunnah" — was not anti-intellectual but anti-speculative. It insisted that the primary obligations of the believer are to revealed knowledge, and that rational arguments, however sophisticated, cannot override authentic textual evidence. This methodological stance became foundational to the Hanbali school and broadly influential across Sunni scholarship.

Third, the Mihna elevated Ahmad ibn Hanbal to a symbolic status that persists to this day. He became the exemplar of scholarly courage — the scholar who refused to compromise on a matter of religion even at the cost of his body's integrity. Ibn Kathir writes that when news of his release spread, people wept with relief across the Islamic world. His funeral drew crowds of hundreds of thousands, with some accounts — likely exaggerated but reflecting genuine sentiment — estimating over a million in attendance.

The theological conclusion that emerged from the Mihna — that the Quran as Allah's Speech is uncreated, while the physical forms of its expression (letters, ink, human voice) are created — became the settled Sunni position, endorsed by Ash'ari, Maturidi, and Athari theologians alike with slightly varying formulations. It is one of the few theological questions on which all three accepted Sunni theological traditions are in substantive agreement.
