According to search-discovered classical Islamic scholarship, the family (الأهل - al-Ahl, or الأسرة - al-Usra) is the cornerstone of a righteous society, established by divine decree as a source of tranquility, love, and mercy. The Quranic framework, elucidated across numerous verses (4:1, 17:23, 30:21), presents the family not merely as a social contract but as a sacred institution for mutual spiritual development. Classical commentators like Al-Qurtubi emphasize the detailed legal and ethical responsibilities that govern family relationships, covering the rights of spouses, parents, children, and kin. Ibn Kathir, in his tafsir, consistently highlights the prophetic examples that model ideal family conduct. Linguistically, the Arabic root of 'Ahl' signifies belonging and worthiness, underscoring the deep sense of identity and mutual support inherent in the Islamic family concept. This synthesis establishes the family as the primary vehicle for transmitting faith, nurturing character, and building a compassionate community.
