What are the financial and material rights of the wife if she requests a divorce, and do these differ from a situation in which the husband divorces her?

The financial rights of a divorced wife include: maintenance (nafaqah) and housing (sukna) during the iddah (waiting period) if the divorce is revocable (raji), or if the wife is pregnant in the case of an irrevocable divorce (ba'in). Also included is mut'ah (a compensatory payment given to the divorced wife), the deferred dowry (sadaq) if it remains owed by the husband, and the maintenance and housing for the children. These rights are due to the wife even if she was the one who sought the divorce, unless her request for divorce was in exchange for a consideration, in which case it is considered khul (a divorce initiated by the wife by returning her dowry or offering compensation). In a khul, she is not entitled to maintenance or housing during the iddah, unless she is pregnant. It is forbidden to seek divorce without a legitimate Sharia reason.
