Key inheritance rulings are laid out in Sūrat al-Nisāʾ. In this domain, a general appeal to fairness is insufficient because particular entitlements are specified by legal texts.
The broad principle is the protection of each person’s right. The actual allocation of inherited property is governed by stated shares and conditions, not by personal preference. Inheritance illustrates that the Qur’an sometimes provides detailed legal distinctions rather than a merely general command. Correct application, however, still requires considering the complete set of relevant texts and legal conditions.
