An Islamic Legal Philosophy: Ibn ʿAbd al-Salam and the Ethical Turn in Islamic Law

Cambridge University PressStudies in Islamic Civilization

My first book explores how medieval Muslim jurists pioneered a crucial ethical turn in Islamic law in a time of social crisis, centering the thought of ʿIzz al-Din Ibn ʿAbd al-Salam (1171-1262 CE). Living in a period marked by political fragmentation, the Crusades, and Mongol invasions, his innovative legal philosophy sought to address these crises by breaking from the dominant formalism of juristic thought towards a more ethical and socially responsive legal discourse. I show how Ibn ʿAbd al-Salam’s legal philosophy reconstituted a new theory of maslaha – the idea of the common good – alongside a hierarchy of legal maxims (qawaʿid fiqhiyya) to render the law more responsive to the crises of his day. 

Ibn ʿAbd al-Salam’s legal philosophy offers meaningful answers to perennial questions debated across legal traditions, such as: What is the source of the law’s authority? Does the law have a purpose, a morality, or an internal rationality? Ibn ʿAbd al-Salam’s unique answers to these questions offers a deep method of legal analysis probing the rationales underlying rulings and studying their outcomes and social effects. Ibn ʿAbd al-Salam prioritizes rationality, morality, and social welfare over formalistic adherence to rules.

Muslim communities suffer from a rampant culture of legalism in which legal rules are commonly treated as outward forms with no principles, purposes, morality, or social ordering behind them. While Ibn ʿAbd al-Salam’s ideas were highly influential in pre-modernity, I believe his legal philosophy can offer Muslims today a new paradigm for understanding and faithfully applying Islamic law in a meaningful way that upholds its integrity and realizes its social benefits.

  • A Tale of Two Tariqas: The Iraqi and Khurasani Shafiʿi Communities in the Tenth and Eleventh Centuries

    Oxford Journal of Law and Religion (2024)

    This forthcoming article reconstructs Shafiʿi legal history during the period of the two tariqas, the Shafiʿi communities of Khurasan and the Iraq in the tenth and eleventh centuries CE. An analysis of these two communities demonstrates how fluid Shafiʿi networks gradually evolved into two discrete communities, separated not only by geography, but also distinguished by diverging interpretive choices, legal authorities and texts, and commitments to rational theology. The study not only complicates our understanding of the what constitutes the postformative madhhab as an institution, but also reveals how broader developments in intellectual and institutional life – such as the ascendance of Ash‘arism, the emergence of new centers of intellectual life, and the introduction of the madrasa – shaped the internal workings of the madhhab.

  • Deceptive Debauchery: Secret Marriage and the Challenge of Legalism in Muslim-Minority Communities

    Religions (2024)

    This article explores the phenomenon of “secret marriages” in Muslim-minority communities through three lenses: the legal, the moral, and the socio-institutional. The article argues that marriage in Islam is a public institution and that while jurists stipulate disparate minimums for contractual validity, the most secret marriage arrangements are considered invalid and prohibited in themselves, or for their entailments, meaning that contracting such a marriage is sinful. The essay highlights the need for public education on Muslim marriage practices that is embedded in a deeper religious morality centering the Sunna to counteract the dominant legalism in the Muslim community that underlies numerous contemporary dilemmas

  • Marriage, Divorce, and Inheritance in Classical Islamic Law and Premodern Practice

    The Oxford Handbook of Islam and Women (2023)

    This chapter examines women’s rights and obligations pertaining to marriage, divorce, and inheritance in classical legal literature (8th to 18th century CE). It summarizes the classical doctrines on these topics according to the four Sunni legal schools and the Twelver Shi‘i school and discusses the scriptural foundations, underlying assumptions, and legal logic underpinning these rules. The chapter further juxtaposes these formal rules with the practice of a range of Muslim societies to demonstrate how Muslims throughout history have employed legal strategies and customary practices to reshape, accommodate, and circumvent formal rules in response to sociohistorical needs. It also shows how other religious discourses besides Islamic law articulate normatively binding moral and religious prescriptions that sit alongside or complicate legal obligations and court-enforceable rights.

  • Judicial Crisis in Damascus on the Eve of Baybars's Reform: The Case of the Minor Orphan Girl (651-55/1253-57)

    Islamic Law and Society (2022)

    This article explores the context and impetus for the Mamluk state-led reform of the judiciary through a contentious court case about a minor orphan girl’s marriage and its dissolution. It reconstructs the procedural problems in Ayyubid courts, which lacked a coherent jurisprudence and institutional oversight to prevent abuses of power by unscrupulous or inept officials. This case exposes the social and institutional dilemmas that the court reform sought to address. It also offers a window onto how Muslim legal institutions evolved in response to social dilemmas and abuses of power.

  • Innovation, Influence, and Borrowing in Mamluk-Era Legal Maxim Collections: The Case of Ibn ʿAbd al-Salam and al-Qarafi

    Journal of the American Oriental Society (2020)

    This article compares al-Furuq, the collection of legal maxims and distinctions authored by al-Qarafi (1228-85 CE), a leading Maliki jurist, with al-Qawaʿid al-kubra, the collection of his Shafiīi teacher, Ibn ‘Abd al-Salam (1171-1262 CE). It demonstrates Ibn ‘Abd al-Salam’s enduring influence on Maliki thought and reveals the tensions surrounding cultures of education and cross-madhhab intellectual influence in thirteenth-century Cairo.

  • The Classical Period: Scripture, Origins, and Early Development

    The Oxford Handbook of Islamic Law (2017)

    This chapter, co-authored with Ahmed El Shamsy and Amir Toft, revisits academic debates regarding the role of the Qur’an and Hadith, respectively, in the formulation of Islamic law. It reviews scholarship on the phases of Islamic law’s development, beginning with the emergence of geographically defined legal traditions and culminating in the formation of the legal schools and their distinctive theoretical principles and substantive doctrines. It concludes by suggesting directions for future research.
