Is it permissible to supplicate for marriage to a specific person after marrying another, while maintaining obedience to the current husband?

A married woman is not permitted to supplicate for marriage to another man. This is considered an transgression in supplication, which is forbidden by Islamic law. She does not know if there is any good for her in it. She must be content with Allah's decree, treat her husband well, and divert her heart from thinking of anyone else.
