According to search-discovered classical Islamic scholarship, the rights of widows and widowers represent a cornerstone of divine justice in Islamic law, centered on the explicit rulings of Quran 4:12. Tafsir by authorities like Ibn Kathir and Al-Qurtubi explains that this verse establishes fixed, unchangeable inheritance shares for surviving spouses, a revolutionary concept that abolished pre-Islamic practices where widows were often treated as property. [3, 12] The husband receives a half or a quarter of his wife's estate, while the wife receives a quarter or an eighth of her husband's estate, with the specific share conditional upon whether the deceased had children. This divine legislation, distributed after all debts and bequests are settled, ensures the financial security and dignity of the surviving spouse. Al-Tabari's historical analysis highlights how these laws fundamentally transformed societal structures, providing widows with economic independence and safeguarding them from destitution and exploitation. [29] The synthesis of these rulings across Islamic jurisprudence confirms that protecting the rights of widows and widowers is a direct command from Allah, central to the family and social structure of Islam.
