Is it considered usury for a husband to take an amount exceeding the value of the loan from his wife's ATM card without her consent?

Summary:

If you borrowed from your husband, and then he withdrew from your card an amount greater than the debt without your consent, the loan is not usurious because an increase was not stipulated. However, the increase he took is not permissible and he must return it to you, unless you willingly consent to waive it for him.
