First, I should verify if "Kitab Azwajan" is a known text. Maybe it's a guide on marriage laws or advice for married couples in an Islamic context. I should check some sources or recall if there's a specific book by that name. Alternatively, it might be a general term for a collection of marriage-related teachings. If the PDF is a fixed version, perhaps it was a common misconception or inaccuracies in previous versions, so the fix corrects those.
