According to the Shariah, who is responsible for the maintenance of a widow?

Answer

The Shariah has an elaborate and just structure for the maintenance of women. If those on whom the Shariah imposes the responsibility fear Allah Ta'ala and discharge their obligation, the widow will have no need for suffering and complaining. A woman is never left destitute by the Shariah.

The responsibility of maintaining a woman whether a widow or an unmarried destitute woman or a divorcee, etc., devolves on her relatives in the sequence of Inheritance.
