To be clear, yes there are alot of different sects in Islam but in Islam there is one core thing that no matter what, it never changes and that is the Quran (Islam holy book). How its preserved is an entirely different topic but its a book which all Muslims no matter the sect should follow clearly.

Islam sects came to be from different interpretations of certain verses by certain scholars but some verses/core messages are very explicit that there is no question about it, its what would put you under the umbrella of "Islam", some which include idolatry and that its absolutely prohibited and that statues have no power and they wont grant you any blessings nor protection. This is what I was referring to when I say we.

Of course some people will still go out of their way to say no or might very clearly misunderstood or be quite misguided because they were illiterate which would lead to believing many such superstitions but it would be quite a stretch to say thats all Islam where its clearly isnt
