Does a woman's use of money saved from her husband without his knowledge and through indirect means affect the validity of her Hajj, knowing that she intends to sell part of this money (gold) to cover Hajj expenses?

A woman who takes her husband’s money without his permission falls into falsehood and injustice. She must repent to Allah, return the money to her husband, and seek his forgiveness. Her need to buy gold does not justify taking money without permission, and the husband is not obligated by Sharia to buy gold for her. It is not permissible for her to perform Hajj with his money except with his permission. If she performs Hajj, her Hajj is valid, but she incurs sin.
