The Text
The document that authorized the killing of thousands of prisoners in the summer of 1988 was not a military order, a court ruling, or an act of parliament. It was a fatwa — a religious decree issued by one man, superseding every law the Islamic Republic had written.
Ayatollah Ruhollah Khomeini’s fatwa was kept secret at the time. Its existence was denied by the regime for years. The text survived because Grand Ayatollah Montazeri — Khomeini’s designated successor, who would pay for his dissent with his political life — preserved it in his memoirs.1
The key passage:
“Since the treacherous monafeqin do not believe in Islam and whatever they say stems from their deception and hypocrisy… and since they have deserted Islam… those who are in prisons throughout the country and remain steadfast in their support for the monafeqin are waging war on God (mohareb) and are condemned to execution.”
Three words carry the entire weight: waging war on God. In Shia jurisprudence, moharebeh is not a metaphor. It is a capital offense — one of the hudud (fixed) punishments in Islamic law, for which no mercy or mitigation is permissible. By declaring imprisoned political dissidents to be mohareb, Khomeini did not merely authorize their execution. He made it religiously mandatory.
The accompanying instruction removed the last guardrail:
“The gentlemen who are responsible for making the decisions must not hesitate, nor show any doubt or concerns with detail… ignore the cumbersome bureaucratic procedures.”
This was not a call for judicial process with reduced standards. It was an explicit order to bypass law entirely.
Three Legal Anomalies
The fatwa violated three principles so fundamental to any legal system — Islamic or secular — that their simultaneous suspension reveals the operation as something other than justice.
First: retroactive capital punishment. The prisoners targeted by the fatwa were not newly arrested suspects. They were people already serving sentences — many of them fixed-term — issued by the Islamic Republic’s own Revolutionary Courts. They had been tried, convicted, and sentenced. Some were months from release. The fatwa retroactively converted prison sentences into death sentences. In legal terminology, this violated res judicata — the principle that a matter already judged cannot be tried again.2 The regime’s own courts had already determined their punishment. The fatwa erased those determinations.
Second: collective guilt. The criterion for execution was not an individual criminal act — not a specific attack, conspiracy, or act of violence. It was a state of mind: “steadfastness” (sar-e moze). Prisoners who maintained their political beliefs — who refused to denounce their former organizations — were condemned to die. The fatwa punished thought, not action. A prisoner who had committed no violence but refused to repent was killed. A prisoner who had committed violence but convincingly recanted could live.
Third: procedural suspension. Khomeini explicitly ordered the elimination of procedural safeguards. No appeals. No delays. No right to counsel. No review. The fatwa did not merely lower the bar for conviction — it abolished the concept of a trial altogether. What remained was a question-and-answer session lasting two to five minutes, after which the prisoner either returned to a cell or was hanged within hours.
No legal system on earth — Islamic, secular, common law, or civil law — permits all three of these simultaneously. Retroactive punishment alone is prohibited by most constitutions. Collective guilt alone was condemned at Nuremberg. Procedural suspension alone defines a state of exception. Together, they constitute something that has no legal category because it is not law. It is administrative liquidation with theological certification.
Two Waves, Two Theologies
The killing proceeded in two distinct phases, each governed by a different charge — a bifurcation that reveals the regime’s need to provide theological justification even while abolishing legal procedure.
Wave 1: Moharebeh — The MEK
The first wave targeted members and supporters of the Mojahedin-e Khalq (MEK), classified by the regime as monafeqin — “hypocrites.” The charge was moharebeh: waging war on God.
The theological logic: the MEK’s National Liberation Army had just invaded Iran from Iraq in Operation Forough Javidan. The regime argued that this invasion made every MEK member — even those who had been imprisoned for years — a combatant in an active war against the Islamic state. Affiliation, not action, was the standard.
The test questions were designed to identify the “steadfast” — those who refused to abandon their beliefs:
- “Are you willing to denounce the hypocrites?”
- “Will you provide information on former comrades?”
- “Will you walk through minefields for the Islamic Republic?”
The last question was not rhetorical. It was a loyalty test: would you die for the regime that imprisoned you? A refusal — or even hesitation — resulted in immediate hanging.
Wave 2: Mortad — The Leftists
The second wave targeted members of secular leftist organizations: the Tudeh Party, Fedaian-e Khalq (both Majority and Minority factions), Komala, and Rah-e Kargar. These groups had no connection to the MEK’s invasion. They were Marxist, communist, or socialist. The moharebeh charge was tenuous.
The regime solved this by shifting the theological category to apostasy — mortad. If a prisoner denied belief in God, they had abandoned Islam. The questions were starkly simple:
- “Do you pray?”
- “Are you a Muslim?”
- “Did your father pray?”
- “Do you believe in God?”
A prisoner who answered honestly — “No, I don’t pray” — was classified as an apostate. But the punishment depended on a further theological distinction:
The Apostasy Categories:
- Mortad-e Fetri (Innate Apostate): a male born to a Muslim father who rejects Islam. Sentence: death. In Shia jurisprudence, an innate apostate cannot repent — his rejection of Islam, having been born into it, is considered irrevocable.
- Mortad-e Melli (National Apostate): a male who was not born Muslim, or who converted and then left. Sentence: imprisonment and torture until repentance.
- Women: In the dominant Shia legal interpretation, female apostates were not to be executed but imprisoned and beaten at prayer times until they repented. This did not mean women were spared — it meant they were subjected to prolonged, gender-specific torture regimes rather than immediate execution.
The father’s prayer habits determined whether his son lived or died. A prisoner whose father prayed was an innate apostate — born Muslim, therefore irreversibly guilty. A prisoner whose father did not pray might be classified as a national apostate — still punishable, but not necessarily by death.
Imagine being asked a single question about your father’s religious habits — and your honest answer determining whether you walk out or are hanged by morning.
This is the granularity of the killing machine. It operated not on evidence of criminal conduct but on theological genealogy. Your father’s relationship to prayer determined whether you were hanged in the morning or beaten until you recanted.
The Steadfast and the Repentant
Before the fatwa, the regime had already developed a system for processing political prisoners: the tavvabin program.
Tavvabin means “the repentant.” Prisoners who agreed to renounce their organizations, provide information on former comrades, and participate in regime propaganda were reclassified as repentant. In some cases, they were forced to prove their loyalty by participating in the torture or execution of fellow prisoners. The system created a moral landscape in which survival required not just submission but complicity.
Those who refused — who maintained their beliefs despite years of imprisonment, torture, and pressure — were classified as sar-e moze: “standing on their position.” The steadfast. They were the primary targets of the fatwa.
This inversion deserves attention. In any moral framework — religious or secular — steadfastness under pressure is typically considered a virtue. Maintaining one’s beliefs despite suffering is the definition of moral courage. The fatwa transformed this virtue into a capital offense. The prisoners who were killed in 1988 were, by the regime’s own classification system, the ones who had refused to break. The survivors were, in many cases, the ones who had agreed to betray.
The Man Who Knew
The illegality of the operation was documented in real time — by the second-highest authority in the Islamic Republic.
Grand Ayatollah Hossein-Ali Montazeri was Khomeini’s designated successor. He had revolutionary credentials no one could question — he had been imprisoned and tortured under the Shah. On August 15, 1988, he met with the Tehran Death Commission. The audio recording of that meeting — later known as the “Montazeri Tapes,” leaked in 2016 — is the single most important piece of evidence about the massacre.
In the recording, Montazeri confronts the commission members directly:
“The greatest crime committed during the reign of the Islamic Republic, for which history will condemn us, has been committed by you. Your names will in the future be etched in the annals of history as criminals.”
He provided a specific number: 750 executed in Tehran “so far” — establishing a verified statistical baseline from inside the system.3
The tapes confirm three things that the regime has spent decades denying:
- The highest officials knew the executions violated both Sharia and state law. Montazeri’s objection was not procedural. It was fundamental — he told the commission that what they were doing was criminal.
- The scale was massive. 750 in Tehran alone by mid-August, with the operation still ongoing and extending to thirty-two other cities.
- The intent was political extermination, not justice. Montazeri understood that the operation was designed to eliminate a category of people, not to punish specific crimes.
The consequence for Montazeri was swift. He was stripped of the succession — removed as Khomeini’s designated heir — and placed under house arrest. He remained under restriction until his death in 2009. The man who spoke the truth about 1988 was punished more severely than any of the men who carried it out.
The Machinery Across the Country
The Tehran commission was the most documented, but the killing was nationwide. Death commissions operated in at least thirty-two cities, each adapting the fatwa’s instructions to local conditions.4
Provincial Commissions:
Province/City Key Members Notes Mashhad (Khorasan) Hassan Mesbah (judge), Hassan Zarif Jalali (prison head) Vakilabad Prison executions Ahvaz (Khuzestan) Ahmadi Shahroudi (judge), Seyyed Alireza Avai (prosecutor) Avai later became Justice Minister Tabriz (E. Azerbaijan) Mirza Najaf Aqazadeh (judge) Signed 250+ death warrants Shiraz (Fars) Ramezani (judge), Eslami (prosecutor), Majid Torabpour (prison director) Adelabad Prison Gilan (Rasht) Nasser Ashuri (IRGC prison head) Highest execution rates of leftists Hamedan Mohammad Salimi (judge) Western border regions
The provincial commissions had the same structure — three members, the same questions, the same two-to-five-minute processing time. The variation was in execution rates and methods. Gilan and Khuzestan had particularly high rates among leftist prisoners. In remote provinces — Kurdistan, Baluchistan — documentation is sparse, and the death toll is likely higher than verified lists suggest.
The scope and simultaneity tell you this was not improvised. Thirty-two commissions operating across a country the size of Alaska, using identical procedures, processing prisoners who had been held incommunicado — this was planned, coordinated, and implemented as a national operation. The fatwa was the authorization. The infrastructure was the machine. The prisoners were the raw material. The output was bodies.
The Machine That Built a State
The summer of 1988 was not an aberration in the Islamic Republic’s history. It was the foundation.
The men who sat on the death commissions did not end their careers in disgrace. They advanced to the highest positions in the state. The massacre was not something the regime committed despite its principles — it was the expression of those principles at their most literal. Moharebeh — waging war on God — is still a charge used by Iranian courts against protesters, journalists, and dissidents in 2026.
When Iran’s current judiciary chief threatens “1988-style” retribution against demonstrators, he is not making a historical analogy.5 He is invoking a precedent — an operational doctrine that the regime has never renounced, never investigated, and never acknowledged as criminal.
The theology of annihilation was not a one-time emergency measure. It is the legal architecture of the state — a mechanism that converts dissent into heresy, heresy into a capital offense, and a capital offense into an administrative procedure that can be executed in two minutes by three men with no legal training, no judicial oversight, and no right of appeal.
The question is not whether it could happen again. The judiciary chief has already told you it will.

Armed opposition (MEK, leftists)
Already-serving prisoners
Female: life + daily lashing
Refusal: execution
