Is the wife's father entitled to object to the husband's selling of his daughter's gold, which was done with her consent and at her request, and is he entitled to reprimand the husband for that, and to what extent does he have authority over his daughter's money?

The gold belongs to the wife, and she may dispose of it as she is an adult and mature. Her father has no right to object except by offering advice, or by preventing her if she is foolish. The wife must return to her husband's house, and obeying him takes precedence over obeying her parents in the matter of separation from the husband, while still showing kindness to her father. The husband has no right to dispose of his wife's property except with her consent and her willing permission.
