What is the ruling of Islamic law and secular law regarding the list of movables, the jewelry, and the deferred mahr, if the wife wishes to relinquish them in order to finalize the divorce after the impossibility of continuing the marital relationship between the spouses?

If a husband divorces his wife unconditionally, she is entitled to her full mahr, including the muqaddam (prompt dowry) and mu'akhkhar (deferred dowry). This also includes the bridal gifts (shabka) and the list of movable assets (qa'imat al-manqulat), unless she seeks khul' (divorce at the wife's instance) by waiving some of her rights. If the wife is not disobedient (nashiz), the husband has no right to pressure her to ransom herself from him with compensation. If he does so, the compensation is void and must be returned. It is imperative to beware of correspondence and conversation between a non-mahram (definition) man and woman without a recognized need, as it is a door to fitna (temptation/strife).
