Is a woman held accountable for a non-mahram man seeing her photos without hijab, which she took with her friends at a private party, if that happened by mistake or without her knowledge?

We have previously clarified that taking and keeping such pictures is impermissible, and there is no benefit in having these pictures on a mobile phone, especially given the potential harm of men viewing them. If some men view them, even accidentally, we fear that you may incur sin for that. Therefore, we advise deleting these pictures to prevent harm.
