Introduction

Salāḥ al-Dīn Yūsuf ibn Ayyūb (532-589 AH / 1137-1193 CE) stands as one of the most consequential figures in Islamic history, a ruler whose recapture of Jerusalem in 583 AH / 1187 CE reversed nearly ninety years of Crusader occupation and restored the sanctity of the first qiblah to the Muslim world. Born in Tikrīt to a Kurdish military family in the service of the Zangid dynasty, Salāḥ al-Dīn rose through the courts of Nūr al-Dīn Zangī before establishing his own Ayyūbid sultanate spanning Egypt, Syria, the Jazīrah, and parts of the Arabian Peninsula. His career embodied the intersection of military genius, political acumen, and sincere religious devotion that scholars of every subsequent generation have studied with admiration. Dr. ʿAlī Muḥammad al-Ṣallābī, the contemporary Libyan historian and Islamic scholar, brings to this biography the same methodological care he applied to his acclaimed studies of the Rightly Guided Caliphs, drawing on classical chronicles including Ibn Shaddād's al-Nawādir al-Sulṭāniyya, ʿImād al-Dīn al-Iṣfahānī's al-Barq al-Shāmī, and Ibn al-Athīr's al-Kāmil fī al-Tārīkh to construct a comprehensive and carefully sourced account.

The book addresses Salāḥ al-Dīn's life across its major phases: his formation under the mentorship of his uncle Asad al-Dīn Shīrkūh and under the broader influence of Nūr al-Dīn's religious reform movement, his consolidation of power in Egypt after the collapse of the Fāṭimid caliphate, his painstaking unification of the fragmented Muslim principalities of the Levant, and finally the great jihad culminating in the liberation of Jerusalem and the subsequent struggle against the Third Crusade. Al-Ṣallābī does not limit his analysis to military campaigns. He gives sustained attention to Salāḥ al-Dīn's administrative policies, his patronage of scholars and jurists, his restoration of Sunnī religious institutions in Egypt, his personal character as described by those who knew him, and the governing principles that shaped his conduct toward enemies and subjects alike. The methodology is broadly narrative and analytical, integrating primary source material with thematic reflection on leadership, governance, and Islamic statecraft.

The scholarly significance of al-Ṣallābī's work lies in its combination of accessibility and academic rigor within an explicitly Islamic framework. Where earlier Western biographies such as Stanley Lane-Poole's classic account approached Salāḥ al-Dīn primarily as a romantic chivalric figure, and where some modern academic treatments focus narrowly on political or economic structures, al-Ṣallābī situates his subject within the theology of jihad, the ideals of just Islamic governance drawn from the Quran and Sunnah, and the long tradition of Islamic biographical literature known as the ṭabaqāt genre. The work has been widely circulated across the Arab world and translated into several languages, finding an audience among both scholars and general readers seeking a thorough treatment grounded in Islamic values.

Readers approaching this biography will benefit from some familiarity with the political geography of the Crusader period and the major dynasties of the twelfth-century Islamic world, though al-Ṣallābī provides sufficient context to orient those coming to the subject for the first time. The chapters proceed largely in chronological order, making it possible to follow the arc of Salāḥ al-Dīn's career from beginning to end, while thematic chapters on character, piety, and administration can be read with profit at any stage. The work is best approached not merely as history but as a study in Islamic leadership, offering the thoughtful reader enduring lessons in how faith, purpose, and character can shape the course of nations.
