You are a muslim and remain muslim till the time you believe that God is one and Prophet Mohammad (PBUH) is the last messenger of God.

So this is the shortest definition of a muslim, while being a muslim your action in your private life could be on the contrary but in that case only God can judge you but when you publically involved yourself with something like idol worshipping which is against the concept that God is one it comes under the category of shirk hence the person involved in such activities cannot be counted as muslim.

A person committing any other crime is accountable for thier sins in court of law during life time or on the the day of judgement in front of the creator but if he still fit in that definition no one can call him non muslim.

But brother max i guess this explain the difference between your billionare friend and shahruk khan, but I am eager to know your beliefs aswell.
