Mulla Sadra's Mizan and Raj'a

The Mizan — Cosmic Balance as Structural Feature of Existence

Surah al-Rahman opens with an account of the divine creation of the cosmos that culminates in a precise statement about its structure: "He raised the heaven and set the Mizan — that you may not transgress the balance. And establish weight with justice and do not make deficient the balance" (55:7–9). The Arabic mizan derives from the root w-z-n, weight and measurement, but the Quranic usage in this passage is cosmic — the balance is a structural feature of the created order that human beings are commanded to respect.

Mulla Sadra Shirazi's philosophy of existence gives this Quranic statement precise ontological content. His doctrine of tashkik al-wujud — the gradation or modulation of existence — establishes that existence is not a uniform quality shared equally by all existents. Rather, existence has intensities: the weakest existence belongs to the lowest material forms; the most intense belongs to God, al-Wajib al-Wujud (the Necessarily Existent). Between these poles, every existent occupies its proper place in the gradient of being. The cosmic order — the mizan — is the arrangement of existents according to their proper station in this gradient.

The implication is precise: the mizan is not a rule imposed externally on an otherwise neutral cosmos. It is the cosmos's own structure. To transgress the balance — to displace what has existential priority — is to disturb the structural order of existence itself. Mulla Sadra's framework makes the Quranic command philosophically coherent: the prohibition on transgressing the mizan is not merely ethical but ontological.

Zulm — The Etymology Mulla Sadra Makes Literal

The Arabic word zulm, conventionally translated as oppression or injustice, carries a root meaning that Islamic commentators have consistently noted: to put something in the wrong place, to misplace, to situate in an improper location. The original application was to the placement of a camel saddle in the wrong position — a practical displacement with harmful consequences. The moral usage extends from this spatial metaphor.

Mulla Sadra's ontology transforms this from metaphor to literal description. If existence has a proper gradient — if every existent has a place in the tashkik hierarchy — then oppression is literally the act of misplacing what has existential priority. When governance authority is removed from the one the divine appointment designated (Ghadir Khumm, 10 AH; Quran 5:3, ikmaltu lakum dinakum) and assigned to a human political arrangement (Saqifa Bani Sa'ida, 11 AH), what occurred is not merely political wrong. The holder of the highest legitimate governance claim in the post-prophetic community was ontologically displaced — put in the wrong place in the existential arrangement that the divine appointment had established.

The pattern repeats with increasing intensity: Fadak displaces the Prophetic House's material rights; Karbala displaces the Imam from his physical existence through the violence of a state claiming Islamic legitimacy. Each act compresses the disturbance of the mizan further. The accumulated displacement is what the Imam Mahdi's appearance must correct — not because a ruler promises justice, but because the structure of existence has a logic of restoration built into it.

Al-Haraka al-Jawhariyya — The Philosophical Ground of Raj'a

The Imami tradition preserves the doctrine of raj'a — the return of certain souls before the Day of Resurrection to witness and participate in the final restoration of justice. The Quranic basis is cited across multiple verses: "And We decreed for the Children of Israel in the Scripture: you will cause corruption in the land twice, and you will be raised to great heights" (17:6); "And the Day when We shall gather from every community a group" (27:83); "And the Trumpet will be blown, and behold — from the graves they hasten to their Lord" (36:51). The theological tradition identifies raj'a as distinct from final resurrection — it is the return of specific souls for specific purposes.

Mulla Sadra's al-haraka al-jawhariyya — the substantial motion of the soul — provides the philosophical grounding for this doctrine without reducing it to an anomaly. Substantial motion holds that substances themselves, not merely their accidents or qualities, are in continuous motion through grades of existence. A soul does not merely have experiences that change its qualities; the soul itself moves through ontological levels. This means that a soul's arc — its trajectory through the grades of being — is a genuine ontological pathway, not merely a biographical narrative.

When oppression cuts a soul's arc short — when the Imam is killed before his governance arc can complete, when Sayyida Fatima a.s. dies within months of the Prophet ﷺ before the Fadak question is resolved — what oppression interrupted is an ontological arc, not merely a life story. The raj'a is not the soul's return to biological life for its own sake. It is the ontological completion of what oppression interrupted: the return to witness the restoration of the mizan that one's oppression had disturbed. This is the philosophical content Mulla Sadra's substantial motion provides — raj'a as ontological fulfilment, not supernatural anomaly.

The Disturbances — Saqifa, Fadak, Karbala as Sequential Displacements

The mizan disturbance is not a single event but a sequence. Each displacement compounds the previous. Mulla Sadra's ontology allows us to describe the sequence with philosophical precision rather than merely narrative indignation.

Saqifa (11 AH / 632 CE) is the governance displacement: the divinely appointed heir, confirmed at Ghadir Khumm ten weeks before the Prophet's ﷺ death, is displaced by a human political assembly convened while the Prophet ﷺ had not yet been buried. The Quranic verse 5:3 — ikmaltu lakum dinakum wa atmamtu alaykum ni'mati, "Today I have completed your religion for you and perfected My favour upon you" — was revealed at the moment of the Ghadir Khumm appointment. The completion of religion included the appointment of its governance heir. Saqifa displaced this before it could operate.

Fadak is the property displacement: the material inheritance of the Prophetic House, given during the Prophet's ﷺ lifetime and therefore not subject to inheritance rules, was seized through an evidentiary violation (a sole-narrator hadith against Quranic text supported by witnesses). The juridical dimension of this displacement is the subject of the companion sub-study Fadak and the Prophetic House Restoration. The ontological dimension is that the material means of the Prophetic House's independence was removed, consolidating the governance displacement of Saqifa into the economic sphere.

Karbala (61 AH / 680 CE) is the existential displacement: Imam Husayn a.s. — the grandson of the Prophet ﷺ, the third Imam, the one in whom the Ahl al-Bayt's living authority was concentrated — was killed by a state claiming Islamic legitimacy. The displacement here is not merely of a life but of the most intense manifestation of the Ahl al-Bayt's living presence. In Mulla Sadra's terms, an existent of the highest legitimate existential intensity in the post-prophetic Islamic world was violently displaced by existents of lower legitimate grade claiming higher position. The inversion of the mizan reached its most extreme expression.

Imam Mahdi as Cosmic Restorer — Necessity, Not Promise

The argument is now complete. The mizan is the structural order of existence according to the gradient of tashkik al-wujud. Oppression — zulm — is the displacement of what has existential priority by what does not. The Saqifa-Fadak-Karbala sequence constitutes a precisely documented set of such displacements, accumulating through fourteen centuries of Islamic history. The cosmic structure requires correction not because a just ruler will one day decide to provide it, but because the ontological logic of the mizan has a built-in requirement: what was displaced must be replaced.

Imam Mahdi's appearance is the event in which this replacement occurs. Bihar al-Anwar (vols. 52–53) records the Imami tradition on the specific governance acts with which his rule begins — including the vindication of the Prophetic House's rights and the public declaration that the governance appointment made at Ghadir Khumm was never legitimately superseded. These are not political programmes. They are the public expression of the mizan's restoration.

The raj'a occurs in this context. The souls whose arcs were interrupted by the Saqifa-Karbala sequence — whose existential journeys were cut short by oppression — return to witness the mizan restored. Sayyida Fatima a.s. returns to see the Fadak principle vindicated. Imam Husayn a.s. returns to witness the governance appointment his death was intended to permanently deny publicly vindicated. These are not simply rewards for suffering. They are the ontological completions that substantial motion requires: arcs completing the journeys oppression interrupted.

This is the philosophical content of the Imam Mahdi's cosmic role. Not the best of rulers. Not the most just of political arrangements. The event in which the structure of existence itself — the mizan that God set when He raised the heaven — corrects the accumulated displacement of fourteen centuries.
