Is there a wisdom behind the waiting period (iddah) of four months and ten days for a widow, even if her husband had not consummated the marriage with her?

The 'iddah (waiting period) for a woman whose husband dies before consummation is four months and ten days. The reason for this is not solely to ensure the emptiness of the womb, as it is obligatory even before consummation. Furthermore, ensuring the emptiness of the womb is achieved by a single menstruation, and because the period is the same for minors, post-menopausal women, and women who menstruate regularly.

Part of the wisdom behind the obligation of this 'iddah is to uphold the husband's rights and emphasize the sanctity of the marriage contract. Death establishes rulings such as inheritance and the entitlement to the dowry. Every ruling in Islamic law has wisdom and meaning. These 'iddah periods are not mere acts of worship; they are obligatory for all categories of women and serve to protect the rights of the spouses, the child, and the second husband.
