<![CDATA[This study examines the conceptual tension between kinship endogamy and the purposes of marriage in Islamic law through a close reading of kafā'ah al-nasab in Abū Bakr al-Dimyāṭī's Iʿānat al-Ṭālibīn, read alongside the wider Shāfiʿī ḥāshiyah tradition on Fatḥ al-Muʿīn (al-Malībārī, al-Bujayrimī, al-Jamal) and al-Nawawī's independent formulations. Marriage in Islamic legal thought serves religious, reproductive, ethical, and familial purposes as well as social ones; this study isolates the social dimension for analysis rather than treating it as marriage's single universal purpose. Using library research with a textual-contextual and intertextual method, the study first separates statements shared across the ḥāshiyah tradition from formulations distinctive to al-Dimyāṭī, then reads the coded material through Jasser Auda's systems approach to maqāṣid al-sharīʿah, with ḥifẓ al-nasl (preservation of lineage) as the primary maqṣad at stake. The analysis shows that al-Dimyāṭī's own text treats nasab-based kafā'ah as a waivable protective right (isqāṭ) rather than an absolute condition, and only gestures toward marriage outside the kinship circle through a caution against ḍaʿf al-shahwah; the broader claim that marriage functions to expand social relations (ittiṣāl al-qabāʾil) is better understood as the author's contemporary reconstruction than as al-Dimyāṭī's explicit doctrine. The study argues that status-based lineage endogamy should be analytically distinguished from marriage between close biological relatives, since only the latter carries documented genetic risk, and proposes reconstructing kafā'ah as a contextual principle balancing dignity, consent, compatibility, and family welfare alongside the other purposes marriage also serves.]]>
