Ghayba Theology: The Hidden Imam Doctrine and the Architecture of Walayah in the Major Occultation (260 AH / 874 CE -- Present)

SCRA Imami Studies Series No. 1. The doctrine of ghayba (occultation) -- the theological teaching that the Twelfth Imam, Muhammad ibn al-Hasan al-Askari (b. 255 AH / 869 CE), entered occultation in 260 AH (874 CE) and remains alive and active in the world -- examined as the most sophisticated institutional response to the post-Saqifa civilizational wound in Islamic history. The paper traces the theological development from the crisis of 260 AH through: the four deputies of the Minor Occultation (260-329 AH), al-Kulayni's Al-Kafi (329 AH) as canonical foundation, al-Saduq's Kamal al-Din (981 AH) as theological systematization, al-Tusi's Kitab al-Ghayba (460 AH) as institutional theology. The Usuli-Akhbari dispute over interpretive authority in the Imam's absence; the development of the marjaiyya as the institutional crystallization of ghayba theology. Haydar Amuli's identification of the Imam as cosmic barzakh (walayah as batin of prophethood) and Mulla Sadra's doctrine of the Hidden Imam as the 'aql fa''al maintaining creation's intelligibility. Khomeini's wilayat al-faqih as political resolution of the ghayba theological problem. The structural parallel between ghayba theology and the Indus basin Sufi qutb doctrine as parallel responses to the same Saqifa wound.
