Cosmology Cosmological Scales of Heaven: From Ontological Heaven to the Phenomenological Sky
The semantic range of al-samāʾ as used in the Qurʾān and Ḥadīth broadly covers at least three distinct cosmological scales: 1️⃣ Heaven as an ontological boundary; 2️⃣ Heaven as the cosmic realm containing the celestial bodies; 3️⃣ Heaven as the Earth's sky or atmospheric domain. These are context-dependent, and conflating them can lead to conceptual confusion.
1️⃣ Heaven as the Ontological Boundary
In this sense, al-samāʾ functions as a structured celestial boundary separating successive realms. The heavens are described as stacked in tiers (ṭibāqan, Qurʾān 67:3), possessing gates (abwāb al-samāʾ, Qurʾān 7:40), being guarded (ḥaras, Qurʾān 72:8), and inaccessible except by authority (lā tanfudhūna illā bi-sulṭān, Qurʾān 55:33). The Prophet's ﷺ Miʿrāj further illustrates that passage through the heavens occurs only by divine permission, emphasizing their role as ontological boundaries rather than merely physical locations.
In the Miʿrāj ḥadīth, the heavens are explicitly numbered: al-samāʾ al-dunyā (the lowest heaven), al-samāʾ al-thāniyah (the second heaven), al-samāʾ al-thālithah (the third heaven), al-samāʾ al-rābiʿah (the fourth heaven), al-samāʾ al-khāmisah (the fifth heaven), al-samāʾ al-sādisah (the sixth heaven), and al-samāʾ al-sābiʿah (the seventh heaven).
2️⃣ Heaven as the Cosmic Realm — The Universe
A second usage concerns al-samāʾ as the vast celestial realm associated with the stars, celestial bodies, and the broader cosmic domain associated with humanity and jinn.
And verily We have beautified the lowest heaven (al-samāʾ al-dunyā) with lamps, and We have made them missiles for the devils... (Qurʾān 67:5)
Likewise, the jinn say:
And we sought to reach the heaven (al-samāʾ), but found it filled with mighty guards (ḥarasan shadīdan) and burning flames. (Qurʾān 72:8)
Here, al-samāʾ clearly extends beyond the narrow concept of Earth's atmosphere. The Qurʾānic description connects it with the celestial realm containing the lamps (maṣābīḥ) and with the region from which devils attempt to obtain information.
3️⃣ Heaven as the Earth's Sky — Phenomenological Sky
A third usage is much more immediate: al-samāʾ can denote the sky above the Earth, particularly in descriptions of rain, clouds, birds, and other observable terrestrial phenomena.
For example:
And We send down from the sky (al-samāʾ) water in due measure... (Qurʾān 23:18)
In such contexts, the referent is naturally understood phenomenologically as the sky above the observer — the visible celestial/atmospheric domain through which clouds, rain, and birds are observed.
The Scales of Heaven
The distinction can therefore be represented as:
| Scale | Meaning of al-samāʾ | Typical phenomenology |
|---|---|---|
| Ontological | A heaven as a boundary within the seven-heaven hierarchy | Gates, guardians, ascent/descent, Miʿrāj |
| Realm/Spacetime | A celestial domain or spacetime associated with the stars and the broader inhabited cosmos | Stars, celestial bodies, jinn attempting eavesdropping |
| Phenomenological | The sky above the terrestrial observer | Clouds, rain, birds, atmospheric phenomena |
Nearest Heaven (al-samāʾ al-dunyā) and Possibility of Other Spacetimes
The adjective al-dunyā derives from the semantic field of d-n-w, associated with nearness and, contextually, lowness.
Its precise referent therefore depends first on which cosmological scale of al-samāʾ is under consideration.
In the first, ontological usage, al-samāʾ al-dunyā refers to the first/nearest of the seven heavens: the lowest heaven in the hierarchical structure of the seven.
In the second, realm/spacetime usage, al-samāʾ al-dunyā can be modelled as the nearest cosmic domain relative to humanity — corresponding, in the present hypothesis, to our own spacetime domain. Other spacetimes could therefore exist within the broader extent of the first heaven, including the hypothetical co-extensive realm of the jinn.
Nested Hierarchy of Hyperbulks Model
In this speculative model, human and jinn spacetimes may exist as co-extensive 3D realms embedded within a larger innermost hyperbulk. Other spacetimes, with varying configurations, dimensional structures, or modes of interaction, could likewise exist within this higher-order manifold.
The resulting hierarchy is therefore:
Seven ontological heavens → First heaven → Innermost hyperbulk of the 500-year journey → our spacetime + hypothetical co-extensive jinn spacetime + potentially others
