Whether a monarchy, communism, theocracy, any kind of despotism or democracy, all systems of government inevitably come up with two classes of people, the ruler and the ruled. The very term 'rule' necessitates a ruling class and a ruled class.
"Democracy is government of the people, by the people, for the people" is quite an attractive statement but in a very subtle manner it conceals, 'over the people'. So, democracy essentially is the government of the majority over the minority. It may sound astonishing but, according to the Qur’an, the majority of mankind is wrongdoers and misguided.
(Verses presented by SA)
10:36 The majority of people follows nothing but conjecture. But conjecture can never be a substitute for the Reality of things. God is Knower of what they do (and forge).
12:106 The majority of those who believe in God, also commit SHIRK.
How about this? "Democracy is government of the people, by the people, for the people, over the people." The majority in a democracy can make any laws against the will of the minority. Even the constitution can be amended to authorize inappropriate moral conduct if the majority so wills. Since this is not a treatise on democracy, we need not go into countless other flaws of the system pointed out by some of the brightest minds.
The Islamic System of government is close to democracy in some ways like the public having a voice and leaders sitting in mutual consultation but there are differences of paramount importance. For example, no amount of majority can trespass the Qur’an and declare alcohol and gambling as permissible. Same goes for homosexuality and mutual cohabitation without marriage, unjust aggression, usury, pornography, prostitution etc.
