Is it obligatory to inform the husband of his wife's actions, such as wearing trousers in his absence, being with a man in a mixed-gender café, attempting to prevent money from reaching the husband's family, lying, hitting her daughter, and neglecting prayer, or should it be concealed?

The woman should be advised and veiled, and warned about the impermissibility of such actions. If she insists on repeating them, there is no objection to informing her husband so that he may prevent her from committing evil. The husband should be advised to return from his journey and take care of his home, or to take his family with him. However, he should not be informed of the details of what is happening.
