Those who oppose Islam are against our way of life and everything we have. They have tried so far to bury Islam in the books and mosques. They never let Islam, neither its government nor its justice be implemented in the external world. If we could introduce Islam to the world the way that it was introduced by past Islamic leaders and if the way it was implemented in the world by certain Islamic governments, all the people of the world would show inclinations toward it.
Sahifeh-ye-Imam, V 11, P 296
