Doing Shirk Unknowingly
Shirk or polytheism is violation to human nature. Without having guidance from God, human can think that their might be one or more creator, but they can never be in a position to assert that they are more than one creator or administrator of this world. In fact, this assertion is the blame on the polytheist. They can’t justify it, why they believe in more than one god, who told them so. That is why they are blameworthy.
