The importance of the history of Imam Hussain's (peace be upon him) life, which has turned into the most tragic epic of human history, is not only because waves of the strongest human emotions are raised on an annual basis during the commemoration ceremonies held for this great personality, but rather there is nothing in his movement other than pure religious devotion and humanistic qualities. The gatherings held in his commemoration do not need any form of introduction or marketing; thus, they are without parallel in their field.
