A friend asked me if we believe in Hadiths I said yes but we differ on unauthentic and authentic sources even in the Shia community. Is that enough or should I specifically tell her that she as a sunni might believe in some I don’t? I’m asking this because she’s considering to marry a Shia man and I’m the only female Shia she knows. And I want to help my friend.

Yeah I think she should be in the know before going into the marriage.
