Introduction

Al-Ḥasan ibn ʿAlī ibn Abī Ṭālib, may Allah be pleased with him and his father, was born in Medina in the third year of the Hijra (625 CE), the first son of ʿAlī ibn Abī Ṭālib and Fāṭimah al-Zahrāʾ, the daughter of the Prophet Muḥammad, upon him be peace. He was among the most beloved of the Prophet's grandchildren, held on his lap, kissed frequently, and described in authenticated narrations as the master of the youth of Paradise. He grew up in the household of prophethood, received direct formation from his grandfather the Prophet and from both his parents, and lived through the caliphates of Abū Bakr, ʿUmar, and ʿUthmān before becoming a central figure in the turbulent events that followed his father's assassination in 40 AH. He died in 50 AH, having lived a life of profound spiritual depth, political significance, and scholarly contribution. This biography, authored by Dr. ʿAlī Muḥammad al-Ṣallābī, is a thorough modern account of his life drawing on the classical sources of ḥadīth, seerah, and history.

The central event of al-Ḥasan's caliphate is his voluntary renunciation of political leadership approximately six months after assuming it, transferring authority to Muʿāwiyah ibn Abī Sufyān in 41 AH, the year that Muslim historians have called ʿĀm al-Jamāʿah, the Year of the Community, because it reunited the Muslim community under a single leadership after a period of devastating civil strife. Al-Ṣallābī examines this decision with care and contextual depth, situating it within al-Ḥasan's own understanding of his religious obligations, his assessment of the political situation, and the authenticated narration in which the Prophet foretold that his grandson would reconcile two great groups of Muslims. Far from being a defeat, the renunciation is presented as an act of foresight and selfless concern for the welfare of the Muslim community, consistent with the character of a man who had internalized the prophetic model of placing the ummah's interests above personal ambition.

Dr. ʿAlī Muḥammad al-Ṣallābī is among the most productive contemporary scholars of Islamic biography and history, known for his extensive series of biographies of the Rightly Guided Caliphs, the senior Companions, and key figures of Islamic history. His methodology combines reliance on primary classical sources, including the major hadith collections, Ibn Saʿd's Ṭabaqāt, al-Balādhurī's Ansāb al-Ashrāf, and al-Ṭabarī's Tārīkh, with a commitment to evaluating narrations critically and presenting the subject from the perspective of Ahl us-Sunnah wal-Jamāʿah. He engages carefully with the polemical literature surrounding al-Ḥasan's life, addressing sectarian misrepresentations and clarifying the authentic record, while maintaining the scholarly objectivity that characterizes serious historical biography.

Readers approaching this biography will find it organized chronologically, moving from al-Ḥasan's birth and upbringing through the events of the early caliphates, his own brief caliphate, his subsequent years in Medina, and his death. Each chapter situates the biographical narrative within the broader historical context, so that the reader comes away with an understanding not only of al-Ḥasan himself but of the formative period of Islamic history in which he lived. Those new to Islamic biography should note that the author's citations of hadith and classical authorities are integral to his argument, not ornamental, and that engaging with them carefully will deepen the reader's appreciation of how Islamic historical scholarship evaluates and uses its sources. The life of al-Ḥasan ibn ʿAlī is a mirror of the prophetic household's qualities: dignity, forbearance, generosity, and an unwavering orientation toward Allah.
