There's an Arabic story about how, long ago there was this village that lived perfectly according to Islamic teachings, and they had a series of great leaders that they loved, but who were still subservient to Allah.
After the line of great leaders died, and the shaitan came to them, and suggested that they build some statues of the leaders, to memorialize them. The people thought this was a good idea and agreed.
But in time, the history behind the statues was lost, and the descendants of the people forgot that they depicted just men. They came to believe the statues themselves were gods, and began to worship them. And so doing they turned away from Allah.
