What is the ruling on a wife taking some of her husband's personal belongings in exchange for her waiver of her legitimate rights after their separation, and why did he accuse her of defaming him by talking about the reasons for her request for divorce?

Marriage and other matters are among God's decrees, for a profound wisdom, and what is obligatory is submission to God's decree. The trial of a husband with an unrighteous wife does not necessarily indicate his corruption, and the consideration is the person's current state, not their past, for repentance erases what came before it. Agreement on divorce in exchange for personal belongings and the forfeiture of certain rights is permissible if the belongings and rights are known in value and quantity; otherwise, the agreement is void. Mentioning the husband's forbidden actions for the purpose of separation is permissible to the extent of need; otherwise, it is a reprehensible defamation that necessitates repentance and seeking forgiveness from the man.
