According to search-discovered classical Islamic scholarship, the principle in Surah Al-Baqarah 2:233, 'No mother should be harmed through her child, and no father through his child,' establishes a foundational rule in Islamic family law. Tafsir by authorities like Ibn Kathir and Al-Tabari clarifies this as a prohibition against either parent using the child as a tool for leverage or to inflict harm upon the other, particularly after divorce. Ibn Kathir explains that a mother should not refuse to nurse the child to cause the father difficulty, nor should the father forcibly take the child from her to cause her anguish. Al-Qurtubi extracts legal rulings from this, affirming the father's financial responsibility for the nursing mother and child, and the invalidity of any action by either parent that prioritizes their dispute over the child's welfare. This divine injunction, rooted in the broader Islamic legal maxim of 'Lā ḍarar wa lā ḍirār' (No harm and no reciprocating harm), ensures that the child's emotional and physical well-being remains paramount, shielded from the potential bitterness of parental separation. Contemporary Islamic jurists affirm that this principle is a cornerstone of child custody and welfare laws, guiding legal decisions to protect the innocent party in any family dissolution.
