Islam and Zoroastrianism
Zoroastrianism is one of the world's oldest monotheistic religions, founded by the prophet Zarathustra (Zoroaster) in ancient Persia and traced to approximately the 2nd millennium BCE. At the time of Islam's emergence in 7th-century Arabia, the Zoroastrian Sasanian Empire was the dominant superpower on Islam's eastern frontier. Persian culture, language, and religious concepts were deeply embedded in the region's intellectual life.
The parallels between Islamic and Zoroastrian belief and practice are extraordinarily specific — extending from the number and timing of daily prayers to the minute details of ritual purification, the structure of the afterlife, the form of angelic hierarchies, and the precise contours of eschatological narratives. Many of these parallels were documented by early Muslim scholars themselves. This page presents them systematically, allowing the reader to assess the evidence directly.
The Divine: God, Angels, and Cosmic Duality
The Concept of God — Tawhid and Ahura Mazda as Monotheistic Frameworks
Allah is singular (tawhid), eternal, and uncreated. In hadith, Allah is described in anthropomorphic terms — possessing two hands, two eyes, a face, and a shin; seated on a throne (arsh) above the seven heavens. He is the sole object of worship, creator of all things, and ruler of the Day of Judgment.
Ahura Mazda ("Wise Lord") is the one supreme deity, uncreated, the source of all truth and light. He is described as possessing wisdom, power, and holiness as distinct divine attributes. He is the sole object of worship, creator of all existence, and the arbiter of the final judgment.
Both traditions insist on the absolute singularity and supremacy of their deity — a marked contrast to the polytheisms surrounding them at the time. The anthropomorphic descriptions in Islamic hadith, while controversial among later Islamic theologians, echo the personalised theism of Zoroastrian texts in which Ahura Mazda acts, speaks, and dispenses justice in ways analogous to a divine king. The structural parallels — omnipotent creator, judge of the dead, sole object of worship, seated in the highest heavens — are striking in both traditions.
The Names of God — 99 Names of Allah vs 101 Names of Ahura Mazda
The 99 Names of Allah (Asma ul-Husna — "the most beautiful names") are a canonical list of divine attributes mentioned in the Quran and hadith. Quran 7:180 commands believers to call upon Allah by these names. Memorising and reciting them is considered an act of worship with spiritual merit.
The 101 Names of Ahura Mazda (Hordad Yasht and the Doa Nam Setayesh prayer) are a canonical enumeration of divine attributes and titles. Reciting the names of Ahura Mazda is an established Zoroastrian devotional practice, believed to confer protection and spiritual merit on the worshipper.
The practice of cataloguing the divine names is attested in Zoroastrian texts that predate Islam by many centuries. The number difference (99 vs 101) is minor; the theological structure — a fixed canonical list of divine epithets, recited for merit — is identical. No other major religious tradition practising at the time of Islam's emergence shares this specific concept.
Angels and Divine Helpers — Islamic Malaika vs Zoroastrian Yazatas
Malaika (angels) are winged spiritual beings created from light, who carry out Allah's commands without question. They include named archangels (Jibril/Gabriel, Mikhail/Michael, Israfil, Azrael) as well as countless lesser angels. They record human deeds, carry divine revelation, guard the righteous, and will blow the trumpet at the end of time.
Yazatas ("worthy of worship") are divine beings created by Ahura Mazda to maintain the cosmic order and protect creation against the forces of Ahriman. They include the six Amesha Spentas (archangels: Vohu Manah, Asha Vahishta, Khshathra Vairya, Spenta Armaiti, Haurvatat, Ameretat) and countless lesser Yazatas assigned to protect nature, time, and righteousness.
Both traditions have a tiered angelic hierarchy: a small number of named archangels with specific cosmic responsibilities, and a vast population of lesser beings. Both depict angels as wholly obedient to God, created to serve and protect, and active agents in human affairs. The Zoroastrian Amesha Spentas and the Islamic archangels share specific functional parallels: both include an angel of revelation, an angel of death, and custodians of paradise and creation.
Battle Between Good and Evil — Allah/Iblis vs Ahura Mazda/Ahriman
Iblis (Satan/the Devil) refused Allah's command to bow before Adam and was cast out of heaven. He was granted respite until the Day of Judgment to lead humans astray. He commands an army of shayateen (demons). The cosmic history is a war between the forces of Allah and those of Iblis, culminating in the final defeat of evil at the Day of Judgment.
Ahriman (Angra Mainyu, "Destructive Spirit") is the supreme evil being who chose the path of the lie from the beginning of creation. He leads an army of Daeva (demons) against Ahura Mazda's creation. The entire cosmic history is a struggle between the Truth (Asha) and the Lie (Druj), which will end with Ahriman's final defeat and the renovation of the world (Frashokereti).
The parallels here are structural and specific: in both cases, the adversary was originally a divine creation who chose rebellion; in both, the adversary is allowed a temporary reign before final defeat; in both, the adversary commands demonic subordinates who tempt humanity; and in both, the cosmic conflict resolves in the complete and permanent triumph of Good. The Zoroastrian Frashokereti (world renovation) maps closely to the Islamic Yawm al-Qiyama (Day of Resurrection) in its structure: judgment, defeat of evil, resurrection of the dead, and the permanent establishment of the divine order.
This dualistic cosmological framework — in which a singular evil being opposes God, commanding demonic forces, and will be ultimately defeated — is Zoroastrian in origin. It is conspicuously absent from the pre-Islamic Arabian polytheist tradition and from early forms of Judaism and Christianity as practised in the region.
Prayer and Ritual Practice
The Call to Prayer — Adhan and the Zoroastrian Bell for Five Daily Summons
Five times daily, a muezzin issues the adhan (call to prayer) from the minaret of a mosque, summoning Muslims to congregational prayer. The adhan uses specific Arabic phrases in a fixed sequence and is among the most distinctive sounds of Islamic practice.
Five times daily, a bell is rung in the Atash Behram (fire temple) or Agiary to summon Zoroastrian devotees to prayer. The ringing marks the transition from one Geh (prayer period) to the next, just as the adhan marks the entry of each Islamic prayer time.
Both traditions use a formal, public auditory signal issued five times daily to summon worshippers to timed communal prayer. The correspondence in number and purpose is exact. The method differs (vocal call vs bell), but the function and frequency are identical.
Five Daily Prayers and Their Timings — Islamic Salat vs Zoroastrian Geh
Muslims are obligated to perform five daily prayers (salat/namaz): Fajr, Zuhr, Asr, Maghrib, and Isha. According to Islamic tradition, the specific number five was commanded by Allah directly to Muhammad during the Night Journey and Ascension (Isra wal-Miraj), starting at fifty prayers and being reduced to five through intercession.
Zoroastrians are obligated to perform five daily Geh prayers (Havan, Rapithwan, Uzerin, Aiwisruthrem, Ushahin). According to Zoroastrian tradition, the correct five-Geh structure was revealed to Arda Viraz by Ahura Mazda during Viraz's celestial journey — a journey in which Viraz visited the heavens and hells to confirm which religious practices were correct.
| Islamic Prayer | Islamic Time | Zoroastrian Geh | Geh Time |
|---|---|---|---|
| Fajr | From true dawn until just before sunrise | Havan | Begins 36 minutes before sunrise |
| Zuhr | Just after noon (solar zenith) until mid-afternoon | Rapithwan | 12:33 PM to 3:00 PM |
| Asr | Late afternoon until just before sunset | Uzerin | 3:33 PM to sunset |
| Maghrib | Just after sunset until the red twilight disappears (some schools: until midnight) | Aiwisruthrem | 72 minutes after sunset until midnight |
| Isha | Around nightfall; ends at dawn | Ushahin | Midnight to 36 minutes before sunrise |
The correspondence here is not merely in the number five — it is in the sequence, the approximate divisions of the day, and the stated origin of each system: both were specifically revealed to a prophet during a celestial journey (see The Celestial Journey). Zoroastrian Geh prayers predate Islam by many centuries and are attested in the Avesta. The Islamic tradition itself attributes the final number (reduced from fifty to five during Miraj) to divine command during the exact same type of narrative that appears in the Arda Viraz Namag.
Note on the word namaz: The word used for Islamic prayer in Persian, Turkish, and Urdu is namaz — a Persian/Avestan word used in Zoroastrianism for centuries before Islam. The Arabic-origin word salat and the Persian/Avestan namaz are used interchangeably in Islamic practice across Persian-influenced cultures.
Following the Movement of the Sun — Solar Timings for Islamic and Zoroastrian Prayers
Islamic prayer times are determined precisely by the position of the sun. Dawn prayer (Fajr) begins at nautical dawn; noon prayer (Zuhr) begins at solar zenith; afternoon prayer (Asr) is calculated by shadow length; sunset prayer (Maghrib) begins immediately at sunset; night prayer (Isha) at astronomical twilight. The sun defines all five intervals.
Zoroastrian Geh prayer times are equally solar. The five Gehs divide the day according to the sun's position: Havan covers pre-dawn through sunrise; Rapithwan covers midday; Uzerin covers afternoon; Aiwisruthrem covers evening and night; Ushahin covers midnight through pre-dawn. The sun is a sacred symbol of Ahura Mazda, and aligning prayer to its movement has deep theological significance.
Both traditions use the sun as the primary clock of worship. This is not incidental: in Zoroastrianism, the sun (Hvare-khshaeta) is a Yazata, a divine being whose movements demarcate sacred time. The Islamic prohibition on praying exactly at sunrise, noon, and sunset (to avoid apparent sun-worship) reflects awareness of this solar framing — and implicitly confirms the solar structure that the prayer times share with the Geh system.
Ritual Purification Before Prayer — Islamic Wudu/Ghusl vs Zoroastrian Padyab/Nahn
Before prayer, Muslims must be in a state of ritual purity. Minor ritual impurity requires wudu (ablution): washing hands, rinsing mouth and nose, washing the face, washing arms to the elbows, wiping the head, and washing the feet to the ankles. Major ritual impurity (after sexual intercourse, menstruation, etc.) requires ghusl — a full ritual bath of the entire body with specific sequence and intention.
Before prayer, Zoroastrians must be in a state of ritual purity. Minor ritual impurity requires padyab: washing of the hands and face with water in a specific sequence before tying the sacred kusti cord and commencing prayer. Major ritual impurity (after contact with the dead, childbirth, menstruation, etc.) requires nahn — a full ritual bath with specific sequence, prayers, and sacred bull's urine (nirang) in the traditional rite.
The correspondence is precise: both have a two-tier purification system (minor washing vs full bath), triggered by the same categories of impurity (sexual activity, menstruation, death), and required before the same religious activity (formal prayer). The specific body parts washed in wudu (face, hands, arms, head, feet) overlap substantially with the padyab sequence. Islamic fiqh manuals devote extensive sections to ritual purity; Zoroastrian practice devotes comparable attention to the same topic in the Vendidad.
Head Covering During Prayer — Taqiyah/Topi Required in Both Traditions
Islamic tradition requires or strongly recommends covering the head during prayer. Men typically wear a taqiyah (kufi cap); women must cover the head (and hair) as part of the prayer dress requirement. Praying with an uncovered head is considered makruh (disliked) or impermissible in many schools.
Zoroastrian practice requires covering the head during prayer for both men and women. Men wear a small topi (cap); women cover their head with a scarf or veil. The head covering is considered mandatory — praying with an uncovered head is an act of disrespect before Ahura Mazda and is religiously prohibited.
Both traditions share the requirement for covered heads during formal prayer, applying this to both men and women. This is distinct from the covering practices of contemporary Judaism (kippah, primarily male) and early Christianity (head covering primarily for women in 1 Corinthians 11). The parallel applies equally to both sexes in both Zoroastrianism and Islam.
Facing a Sacred Direction During Prayer — Qiblah vs Sacred Fire
During prayer, Muslims face the Kaaba in Mecca, the direction known as the qiblah. Mosques mark the qiblah with a wall niche (mihrab). The obligation to face the qiblah is non-negotiable; prayers performed facing the wrong direction without excuse are invalid. The Kaaba contains the Black Stone and is understood as the axis of the world and the house of God.
During prayer, Zoroastrians face a central blazing fire — the sacred flame kept perpetually burning in the fire temple (Atash Behram). The fire represents the divine grace of Ahura Mazda and the cosmic principle of truth (Asha). Prayers must be directed toward the visible fire, which functions as both sacred centre and directional focus of worship.
Both traditions require prayer to be directed toward a specific sacred focal point: a physical location containing a divine symbol (the Kaaba as God's house; the fire as God's presence). The Quran itself (27:8) describes the divine voice speaking "from the fire" in the narrative of Moses, and 37:1–4 invokes the concept of structured ranks (of those who pray). Some scholars have noted that the earliest Islamic prayer direction was toward Jerusalem before being changed to Mecca, suggesting the qiblah concept itself was being adapted.
Reciting Scripture in Its Original Language — Arabic in Islam, Avestan in Zoroastrianism
Islamic prayer requires recitation of Quranic passages in Arabic. A translation into another language does not fulfil the obligation of salat — even for worshippers who do not speak or understand Arabic. The Fatiha (opening chapter) must be recited in Arabic in every rak'a (unit of prayer) as a mandatory pillar of the prayer.
Zoroastrian prayer requires recitation of Avestan texts (the Gathas and Yashts) in the Avestan language — an extinct language that the vast majority of Zoroastrian worshippers have not spoken for centuries. Recitation in a vernacular translation does not fulfil the devotional obligation. The sacred language is itself considered spiritually potent beyond its semantic meaning.
Both traditions share the unusual requirement that formal prayer must use the original sacred language regardless of the worshipper's comprehension. This is a distinctive feature: most religious traditions prioritise understood prayer over linguistically correct but incomprehensible recitation. In both Islam and Zoroastrianism, the precise phonetic form of the recitation is considered sacred and functionally separable from meaning.
Daily Supplications for Life's Occasions — Islamic Duas vs Zoroastrian Nirangs
Islamic tradition prescribes specific duas (supplications) for virtually every action of daily life: waking, sleeping, eating, drinking, entering and leaving the bathroom, dressing, entering and exiting the home and mosque, travelling, rain, thunder, entering a new month, and so on. These are recorded in collections such as Hisnul Muslim (Fortress of the Muslim) and are memorised in Arabic.
Zoroastrian tradition prescribes specific nirangs and short prayers (afrinagans) for the same range of daily actions: waking, sleeping, eating, cutting nails and hair, using the bathroom, dressing, entering a new room, undertaking journeys. These are recorded in prayer manuals and recited in Avestan. The Khordeh Avesta (the "small Avesta") is precisely such a compendium of daily prayers.
Both traditions extend the sphere of formal religious observance into every routine moment of daily life through scripted prayers in the original sacred language. The Islamic du'a system and the Zoroastrian nirang system are structurally identical in concept: fixed sacred-language formulas attached to specific life actions, memorised and recited as an act of worship.
The Celestial Journey
The Ascension to Heaven — Islamic Miraj vs Zoroastrian Arda Viraz
Isra wal-Miraj (Quran 17:1, 53:1–18): Muhammad is transported overnight from Mecca to Jerusalem on a celestial steed (Buraq), then ascends through seven layers of heaven, meeting earlier prophets (Adam, Jesus, Joseph, Idris, Aaron, Moses, Abraham) stationed at successive levels. He is received in the presence of Allah, receives the command to pray fifty times daily, and — through Moses's advice and repeated intercession — negotiates it down to five. He is shown paradise and hell on his journey.
Arda Viraz Namag ("Book of the Righteous Viraz"): The pious man Viraz is chosen by the Zoroastrian community to make a spiritual journey to confirm correct religious practice. After being given a sacred drink (haoma wine mixed with milk), he falls into a deep sleep and his soul ascends through the heavens, guided by the archangel Sraosha and the Yazata Adar. He meets the souls of the righteous and learns the rewards of heaven; he is then shown the torments of hell in vivid detail. He returns and reports the findings — specifically confirming the correct number and form of the five daily prayers.
The structural parallels between Miraj and the Arda Viraz narrative extend to the smallest details:
- A single righteous man is chosen for the journey.
- The journey involves a temporary departure from the body or physical world (night journey; induced sleep/death).
- The traveller ascends through multiple layers of heaven.
- He is guided by an angelic companion throughout.
- He meets earlier righteous souls or prophets at successive levels.
- He witnesses both paradise and the torments of hell.
- The central purpose of the journey is to receive or confirm the correct number of five daily prayers.
- He returns to the world to report what he has learned.
The Arda Viraz Namag is attested in Pahlavi (Middle Persian) texts that predate Islam's emergence. It represents centuries of Zoroastrian tradition about heavenly journeys. Islamic scholars have historically been aware of this parallel; some classical authors noted the similarity without drawing the same conclusion that modern comparative scholars do.
The historical record raises additional questions consistent with the borrowing thesis. The Quran (17:1) states Muhammad was taken to al-Masjid al-Aqsa (the Farthest Mosque) in Jerusalem — but no mosque existed in Jerusalem in 621–622 CE. The original al-Aqsa mosque was built by Caliph Umar in 638 CE, sixteen years after the alleged journey, on a site described as a rubbish heap at the time of the Muslim conquest (Al-Tabari, Vol. 12). The Dome of the Rock — from which Muhammad allegedly ascended to heaven according to later Muslim tradition — was not built until 691 CE. A narrative borrowed from an existing Zoroastrian archetype and retrospectively set in Jerusalem would naturally lack accurate knowledge of Jerusalem's actual built environment in 622 CE.
Contemporary accounts confirm early scepticism. Umm Hani bint Abi Talib — Muhammad's own cousin, in whose house he slept that night — pleaded with him not to tell people: "Don't tell the people about this for they will know you are lying and will mock you." Ibn Ishaq records that many Muslims apostatised upon hearing the story (Sirat Rasulullah, trans. Guillaume, p. 183). For the theological contradiction between the Miraj's implied direct vision of God and Quranic verses stating that no human can see God — contradicted explicitly by Aisha — see the Contradictions page.
Afterlife and Eschatology
The Word "Paradise" — Al-Firdaus Borrowed from Avestan Pairidaeza
The Quran uses two primary words for the afterlife abode of the righteous: al-Jannah (the Garden) and al-Firdaus (the highest garden/paradise). The latter appears in Quran 18:107 and 23:11 as the supreme level of paradise. Arabic lacks the phoneme /p/, so the Persian word Pirdaus became Firdaus in Quranic Arabic — a direct borrowing.
The word "paradise" derives from the Avestan pairidaeza — meaning a walled enclosure or royal garden. It passed into Old Persian as pairi-daeza, into Middle Persian (Pahlavi) as Pirdaus, into Greek as paradeisos (from which English gets "paradise"), into Arabic as Firdaus, and later into all Islamic languages. The concept of a walled garden of abundance as the afterlife reward is Zoroastrian in origin.
This is a documented linguistic borrowing, not a structural parallel. The Quranic use of Firdaus is a direct loan from Persian/Avestan Pirdaus/pairidaeza. The word entered Arabic — whose phonology lacks /p/ — with the standard substitution of /f/. This is one of many Persian and Aramaic loanwords in the Quran, reflecting the cultural environment of 7th-century Arabia. The word was already in Greek as paradeisos (used in the Septuagint to translate the Garden of Eden) before Islam.
Heaven and Hell — Jannah/Jahannam and Garō-nmāna/Druj-ō-dəmāna
Islamic heaven (Jannah) is a physical realm of eternal pleasure: rivers of water, milk, wine, and honey; lush gardens; palaces; abundant food; and the company of heavenly maidens (houris). Islamic hell (Jahannam) is a physical realm of fire, boiling water, festering wounds, and unceasing torment, with specific punishments matched to specific sins.
Zoroastrian heaven (Garō-nmāna, "House of Song") is a realm of eternal light, joy, and communion with Ahura Mazda. Zoroastrian hell (Druj-ō-dəmāna, "House of the Lie") is a realm of permanent darkness, stench, putrid food, and suffering, with punishments specifically corresponding to sins committed in life. The Arda Viraz Namag describes these torments in vivid matching detail.
The Islamic descriptions of hell's punishments in Quranic and hadith texts — specific punishments assigned to specific moral failings, described in graphic physical detail — parallel the Arda Viraz Namag's catalogue of hell torments with notable specificity. Some Islamic descriptions of hell (eating from the Zaqqum tree whose fruit resembles "molten copper," the boiling fluid forced down throats) share imaginative space with Zoroastrian descriptions of hell's particular tortures.
The Bridge Over Hell — Islamic Pul-Sirat vs Zoroastrian Chinvat Bridge
Pul-Sirat (or al-Sirat al-Mustaqim in its eschatological sense): on the Day of Judgment, all souls must cross a bridge over the fire of hell. The bridge is described in hadith as thinner than a hair and sharper than a sword. The righteous cross it swiftly, while the wicked stumble and fall into hell below. (Sahih Muslim 195a)
Chinvat Bridge (Chinvato Peretu, "Bridge of the Separator"): after death, all souls must cross this bridge over hell. For the righteous, it widens to twelve leagues and is easy to cross; for the wicked, it narrows to a razor's edge and they fall into hell below. The bridge is guarded by the Yazata Mithra and his companions, who judge the soul before it crosses.
The Chinvat Bridge is one of the most ancient elements of Zoroastrian eschatology, attested in the Gathas (the oldest hymns of the Avesta). The Islamic Sirat bridge appears in hadith (not the Quran directly), and the description — thinner than a hair, sharper than a sword — structurally mirrors the Chinvat's narrowing to a razor's edge for the wicked. The narrative function is identical: the bridge separates the righteous (who pass) from the wicked (who fall), serving as the final physical test of moral worthiness.
The Questioning of the Dead — Munkar & Nakir vs Mithra, Sraosha & Rashnu
After burial, the soul is questioned in the grave by two terrifying blue-black angels, Munkar and Nakir, who ask: "Who is your Lord? What is your religion? Who is your Prophet?" Correct answers lead to a peaceful, wide grave and a window to paradise; wrong answers result in the angel striking the soul with an iron hammer and the beginning of the azab al-qabr (torture of the grave). (Sahih Muslim 2870)
On the fourth day after death (dawn of the fourth day — Chinvat ceremony), the soul is met and questioned by three divine judges: Mithra (angel of covenants and truth), Sraosha (obedience/hearing), and Rashnu (justice/equity). Rashnu weighs the soul's good deeds against bad on a divine scale. The outcome determines whether the soul crosses the Chinvat Bridge to paradise or falls to hell.
Both traditions place a formal divine questioning of the dead immediately after death, with angelic judges who determine the soul's fate. In both, the questioning concerns religious identity and moral conduct. The Islamic questioning occurs in the grave before resurrection; the Zoroastrian questioning occurs at the Chinvat Bridge before crossing. The most notable parallel is the specific number-and-nature of judges (Islamic: 2 named angels; Zoroastrian: 3 named divine beings) and the immediate consequence of the verdict (punishment begins at once for the wicked in both systems).
Prayers and Intercessions for the Dead — Hadiyyat al-Thawab and Muktad Ceremonies
While every soul will be judged on its own deeds, Islamic tradition holds that living family members and friends can benefit the dead through prayer (du'a), Quran recitation, sadaqah jariyah (ongoing charity on the deceased's behalf), and hadiyyat al-thawab (gifting spiritual merit). Special prayers on the 3rd, 7th, 40th days and the anniversary after death are widely practised.
Zoroastrian tradition holds that the souls of the dead return during the ten-day Muktad period (also called Frawardigan). Living relatives perform ceremonies, light fires and incense, and recite specific prayers (Afrinagan) to comfort and benefit the souls. These prayers and good deeds performed in the name of the deceased are believed to ease their afterlife conditions.
Both traditions maintain the theological position that individual judgment is primary and based on personal deeds, yet both also affirm that living family members can still improve the deceased's condition through specific ritual acts. This combination of individual accountability with intercessory ritual is a distinctive feature shared by both traditions.
Further Eschatological Parallels — Mahdi/Saoshyant, Barzakh/Burzaxw, Houris/Daena, A'raf/Hamistagan
Key Islamic eschatological concepts include:
- Al-Mahdi — the awaited saviour who will come in the last days to restore justice
- Barzakh — the intermediate state between death and resurrection
- Houris — beautiful heavenly maidens who greet the souls of righteous men in paradise
- Sidrat al-Muntaha — the lote tree at the boundary of the seventh heaven, beyond which none may pass
- Al-A'raf — a borderland between paradise and hell for souls whose deeds are exactly balanced (Quran 7:46–49)
Corresponding Zoroastrian eschatological concepts:
- Saoshyants — three saviour figures who will appear in the last days to resurrect the dead and bring about final renovation
- Burzaxw (Hamistagan) — the intermediate state between death and final judgment
- Daena — a beautiful maiden (or hag, for the wicked) who meets the soul at the Chinvat Bridge and represents the soul's own accumulated deeds
- Humaya tree — a sacred tree at the boundary of the heavens, beyond which the divine light is
- Hamistagan — a middle abode for souls whose good and bad deeds are equal, neither in paradise nor hell
The point-for-point correspondence of these eschatological concepts is striking. The saviour-figure tradition (Mahdi / Saoshyant) shares the same narrative role: a future messianic figure who ushers in the final age of justice. The "borderland" concept (A'raf / Hamistagan) solves the same theological problem: what happens to souls with exactly balanced deeds? The heavenly maiden imagery (Houris / Daena) and the boundary tree (Sidra / Humaya) are specific imaginative elaborations without parallel in the Abrahamic traditions surrounding early Islam.
The intermediate state (barzakh / burzaxw) is of particular note: the very word barzakh, used in Quran 23:100 and 55:20 for a barrier or intermediate state, is a Persian loanword. Its Pahlavi cognate burzaxw is found in Zoroastrian eschatological texts describing the same intermediate realm between death and final judgment.
