A Historical Perspective
Yazid ibn Muawiyah: Without doubt, the biggest contributor to the shedding of Imam Husain's (a.s.) blood and its main proponent was Yazid ibn Muawiyah. And that is not exactly surprising when we consider that Yazid is the one who inherited apostasy, tyranny and blasphemy from his father. He was the grandson of Abu Sufyan and the son of Muawiyah.
Sorrow and Grief for the Martyrs of Karbala
The Universe Mourns: Imam (a.s.) said: "Then indeed the seven skies wept on his (Imam Husain) killing, the seas along with their lashing waves erupted into crying. The skies along with their pillars shed tears. The earth along with its elements, trees along with its branches, seas along with their waves and their inhabitants including fishes, the noble angels and the celestial residents, all mourned his martyrdom." (al-Lohuf, p. 222)
Liberated is the one who grasps the greatness of "Hurr"
When the morning of Aashura dawned, the chapter of the biggest victory in history was opened. Hurr placed the standard of freedom on his shoulders and ordered that his hands be tied behind his back and he be blindfolded. His son, brother and slave accompanied him. Despite being among the earthly creatures, the embodiment of repentance, Hurr, managed to stir amazement in the celestial inhabitants.
Importance, Rewards and Effects
Ziyaarate Aashoora: Emphasis of Imam-e-Zamana (a.t.f.s.) : The emperor of the era, the friend of Allah, the chief of the universe, Imam-e-Zamana (a.t.f.s.) has forcefully stressed the importance of reciting Ziyaarate Aashoora in his letters and sayings.
Imam Husain (a.s.) and the Holy Ka'bah
Imam Jafar Sadiq (a.s.) narrates: 'Imam Husain (a.s.) never suckled anyone. When the Holy Prophet (s.a.w.a.) used to come he would place his tongue into the mouth of Imam Husain (a.s.) so much so that he would get drenched with milk. Allah has made Imam Husain's (a.s.) flesh and blood from the flesh and blood of the Holy Prophet (s.a.w.a.).' (Behaarul Anwaar, vol.43, pg. 425; Al-Awaalim vol. 17, pg. 24)
