The belief that it was the uprising of the Master of Martyrs that preserved Islam is really a correct belief. This event has become livelier, on a daily basis, in the course of time and after the passage of many centuries. Today, this ceremony is being held in a warmer and more enthusiastic and comprehensive manner than a hundred years ago when Muharram did not apparently have opponents like today's opponents. All these matters reveal certain truths and it is suggestive of an orientation which is moving forward in the world with the leadership of Hussain ibn Ali (God's greetings be upon him). By Allah's favor, this orientation will move forward and will resolve the problems of nations.

Today, Imam Hussain (a.s.) is known to the world more than he was 5 centuries, 10 centuries ago. Today the situation is as such that when impartial intellectuals learn about the history of Islam, and the story of Imam Hussain (a.s.), they feel humble. Even for those who do not know anything about Islam, yet they recognize the notions of freedom, justice, dignity, elevation, and lofty human values, Imam Hussain (a.s.) is an invaluable role model in seeking liberty and justice, in rising up against vices and evils as well as in fighting ignorance and humiliation of mankind.
