In some Muslim societies today, a marriage gift of a hundred thousand dollars in diamonds is not unusual. The bride retains her marriage gifts even if she is later divorced. The husband is not allowed any share in his wife's property except what she offers him with her free consent. The wife's property and earnings are under her full control and for her use alone since her, and the children's, maintenance is her husband's responsibility. No matter how rich the wife might be, she is not obliged to act as a co-provider for the family unless she herself voluntarily chooses to do so.
Spouses do inherit from one another.
Moreover, a married woman in Islam retains her independent legal personality and her family name. She is a solar planet with a name and legal personality of her own.
