Ismaili Ta'wil of al-Shams wal-Qamar — The Sun and the Moon: How the Quranic Pair of Sun (Shams) and Moon (Qamar) — 'The Sun and the Moon With Reckoning' (55:5), 'He Made the Sun a Radiance and the Moon a Light' (10:5) — Are Read in Ismaili Cosmological Ta'wil as the Natiq (Prophet-Lawgiver) and the Asas/Imam (Who Reflects and Transmits the Natiq's Light Into the Batin Dimension) — How the Sun Gives Its Own Light While the Moon Reflects, and Why This Makes the Imam's Role Structurally Dependent on and Yet Distinct From the Prophet's

In Ismaili ta'wil, al-Shams wal-Qamar (الشَّمسُ وَالقَمَر — The Sun and the Moon; the two great celestial luminaries that structure time and reckoning; Quranic occurrences: [1] 55:5 'al-shamsu wa-l-qamaru bi-husban' [the sun and the moon with reckoning/calculation]; the paired luminaries govern time's structure; [2] 10:5 'huwa alladhi ja'ala al-shamsa diya'an wa-l-qamara nuran' [He is the one who made the sun a radiance/blaze [diya'] and the moon a light [nur]]; the critical distinction: diya' [radiance, its own luminosity] vs. nur [light, reflected light]; the sun is self-luminous; the moon gives nur [reflected light, not its own]; [3] 91:1-2 'wa-l-shamsi wa-duhaha / wa-l-qamari idha talaha' [by the sun and its splendor / and the moon when it follows it]; [4] 36:40 'la al-shamsu yanbaghi laha an tudrika al-qamara wa-la al-laylu sabiqu al-nahar' [it is not for the sun to overtake the moon, nor the night to outstrip the day]; each has its own appointed course; the Ismaili cosmological ta'wil: Ismaili ta'wil maps the sun-moon pair onto the Natiq-Asas/Imam pair — the two-office structure at the center of Ismaili prophetology; [1] al-Shams [the Sun] = al-Natiq [the Speaking Prophet/Lawgiver]: the Natiq is the prophet who brings new shari'a — a new cycle of divine law; like the sun, the Natiq is self-luminous: the Natiq's revelation comes directly from the divine source; the prophets of the Ismaili six-cycle schema [Adam, Nuh, Ibrahim, Musa, 'Isa, Muhammad] are each a Natiq = a Sun for their era; [2] al-Qamar [the Moon] = al-Asas [the Foundation/Wasi] and Imam: the Asas is the Natiq's immediate successor who inherits the batin of the Natiq's revelation; like the moon, the Imam gives nur [light/guidance] but this nur is reflected from the Natiq's diya'; the Imam does not bring new shari'a [new light] but transmits the batin of the existing shari'a [reflected light]; Adam's Asas = Sheeth; Ibrahim's Asas = Isma'il; Musa's Asas = Harun [Aaron]; 'Isa's Asas = Sham'un [Simon Peter]; Muhammad's Asas = 'Ali ibn Abi Talib; [3] the distinction between diya' and nur: the 10:5 distinction is crucial in Ismaili ta'wil: the Natiq's revelation is diya' [self-originating radiance]; the Imam's walayah is nur [reflected and transmitted light]; both illuminate; neither can be without the other [the moon is dark without the sun; the sun's light only reaches earth at night through the moon's reflection]; [4] 36:40 'each in its appointed course': the sun and moon do not interfere with each other's movement; in Ismaili ta'wil: the Natiq's function [zahiri legislation] and the Imam's function [batin transmission] are distinct and non-interfering; each has its role in the cosmic structure; [5] 91:1-2 'the moon when it follows [the sun]': the moon follows the sun but does not merge into it; the Asas/Imam follows the Natiq in cosmic order but maintains distinction; [6] the sun-moon pair as a model of knowledge transmission: the Natiq's shari'a is like sunlight — powerful, illuminating, but potentially blinding without the mediation of the batin; the Imam's ta'wil is like moonlight — gentle, accessible, appropriate for the night of the zahir-dominant era in which the Fatimid dawr al-satr was situated) is one of Ismaili cosmology's most evocative symbol-pairs.
