According to search-discovered classical Islamic scholarship, the concept of Al-Murdi'ah (المرضعة), the nursing mother or wet nurse, transcends a mere biological function to establish profound legal rights and sacred kinship ties within Islamic law. Tafsir by authorities like Ibn Kathir on Quran 2:233 clarifies that this role comes with divinely mandated rights, including the father's responsibility for the mother's sustenance and clothing during the recommended two-year nursing period. Furthermore, Al-Qurtubi's juridical analysis of Quran 4:23 explains that the act of nursing creates Rada'ah (milk kinship), a unique bond that makes the nursing woman a 'milk mother' to the child, establishing marriage prohibitions equivalent to those of blood relations. This synthesis across multiple verses demonstrates that Al-Murdi'ah is a pivotal role in Islam, safeguarding the rights of women and children, and expanding the concept of family to strengthen community bonds.
