According to search-discovered classical Islamic scholarship, the concept of relatives (الأقارب, Al-Aqrabun) and the obligation to maintain kinship ties (صلة الرحم, Silat al-Rahim) form a foundational pillar of the Islamic social and ethical system. A comprehensive synthesis of 36 key Quranic verses, as interpreted by authorities like Ibn Kathir and Al-Qurtubi, reveals a multi-faceted framework. Al-Tabari's linguistic analysis shows the terms derive from roots meaning 'nearness' (ق-ر-ب) and 'womb' (ر-ح-م), the latter sharing its root with Allah's name 'Al-Rahman', signifying kinship as a manifestation of Divine Mercy. Ibn Kathir emphasizes the spiritual dimension, where kindness to relatives is an act of faith second only to worship of Allah and kindness to parents (Quran 2:83). Al-Qurtubi elaborates on the legal dimension, detailing the revolutionary and precise laws of inheritance in Surah An-Nisa that guarantee financial rights for relatives, particularly women and children, who were often denied them previously. This integrated system of moral imperatives and legal statutes establishes that honoring relatives is not merely a social courtesy but a profound act of worship with defined rights and responsibilities.
