Islam was on the verge of disappearing within the throat of the tyrants and justice being crushed under the stampede of evildoers. The cruel rule of Yazid and his men was about to cross the shining face of Islam away by a red line and the agonies and troubles suffered by the great Prophet of Islam (s) and the early-day Muslims as well as the blood of the self-sacrificing martyrs, were about to be forgotten and gone to the winds.
It was at this point that Imam Husayn (PBUH) set out on the great Ashura uprising. The Master of Martyrs rose to strengthen Islam, to oppose cruelty, and to stand up against the empire of those days that were beyond the scope of modern day empires.
