I would like to start off by thanking the Shiachat community for their sincerity. The anonymous nature of the internet is sometimes a great luxury. It is questions like these that I do not think that I would get a sincere response to in real life.
My question to my Shia siblings: What is the ruling on one that does not believe in the Imams?
Before responding, I want you to remember that I do not want your personal opinion, but I want proper evidences.
