Imam Husain's (A.S.) Martyrdom Corrected the Course of Humankind

Imam Husain (A.S.) was a heavenly candle in the stormy winds of this world whose light saved the gloomy path of humanity from ignorance and darkness and brightened the alleyway of life and belief. Drops of the melted candle of his heavenly body irrigated the sapling of Islam his celestial movement has been training devoted believers who, with their tears have been keeping his memory and the tree of faith alive.
Imam Husain (A.S.) was the third infallible Imam, appointed by God, the son of Ali and Fatima (A.S.), daughter of Holy Prophet Mohammad (S.A.W.). He, with his family and few companions, stood against the multitude of equipped transgressors and courageously resisted to their last breath. They knew, from the start, that they were going to be martyred that day the Ashura in the land of Karbala; Holy Prophet (S.A.W.), many years before, had prophesied about it. His movement was neither a revolution to occupy the government, nor a movement to gain power, but rather it was a unique, one of a kind, movement in history which occurred in order to warn human and to correct the course of humankind. He, for enlightenment of monotheist, started his movement, to revive Divine human values. Continual mourning of the Shi'ah, on anniversary of the Ashura every year, reminds humanity that Ashura is an everlasting, destiny-making and meaningful epic and it is not just another forgotten page of history.
Deceits of the power-hungry brought about circumstances by which, after Imam Ali(A.S.), non of the rightful infallible Imams (A.S.), appointed by God, openly ruled the government of Muslims and as the result today, the world is suffering from inequalities, injustices and inhumanities.
However, will it always be this way? Humanity is eagerly and anxiously awaiting the Appearance of the Saviour of humankind, the last infallible Imam, the final bridge between the Creator and the created, the one whom followed by his emergence, pure ones such as Jesus (A.S.) -with God's permission- shall return to assist and help him. At time of Mahdy (A.S.) , Imam Husain(A.S.) shall also return and so will the ones who, in any way, caused his martyrdom. Those so-called humans shall face the Divine justice of Prophet Muhammad (S.A.W.) and his progeny (A.S.) in this world before their everlasting life in Hell. According to Qur'an, they shall say:
They shall say : Our Lord! You have made us to die twice, and You have given us life twice; now that we are confessing to our sins, is there a way out? (The Holy Qur'an,Surah Mo'men,Verse 11)
That which was done against Imam Husain (A.S.) was the most heart-breaking crime against the best creations of the Creator, in addition to that, it was the darkest crime against humanity. Like Eblis (Satan) who stood against Adam and did not recognize Adam's Divinely bestowed position, those who stood and are standing against the Ahl al-Bayt(A.S.) and did not accept and are not accepting the heavenly bestowed exalted position of the Ahl al-Bayt(A.S.), have actually been standing against God and His command, therefore, they have been blocking human's path to eternal bliss. Thus, their sin -which they have chosen to commit- is unforgivable and if one dies with this sin and belief, there shall be no way out of God's punishment.
