If we look back to the era of the Prophet Muhammad PBUH and the Era of Companions, we can find other prespective to see political system which we can compare to the democratic system.

But, the most important point is that Muslim must consider the concept of shura, whereas shura/musyawarah is been recognized as a core value of democracy.
