Sheikh in my fatherís office there is a picture on the wall. In this picture ya Ali is written. I told my father this is not right but he did not listen to me. He did not hang this in fact it was alredy there when he bought the office. Is it shirk/kufr if i go to that office?

Hanging such a picture is wrong and saying ya Ali is means of shirk! There is no sin upon you once you have advised him or upon entering that office.*
