What is the ruling on photographing someone's conversations and sending them to another person without causing harm? If it is not permissible, then what are the consequences for someone who did so out of ignorance and is unable to retrieve the conversations, and is he required to delete his account?

It has been previously explained that it is not permissible to photograph someone without their permission, and this prohibition is even more emphasized for video recording. The recorded clips should be retrieved or deleted. If that is not possible, then it is sufficient to resolve not to repeat it in the future and to regret what has passed. If the person concerned with the photography were informed and asked for forgiveness, it would be more appropriate and would absolve one's conscience, provided that informing them does not lead to evil between them.
