On the birth of Imaam Hussain, it was prophesied that the faith of Islam would be rescued by him. Umayyad ruler, Mu’awiya appointed his son Yazid as his successor, who was one of the most licentious of men. The people, fearing death and destruction at the hands of the tyrant, had yielded to him out of fear. Yazid demanded allegiance from the Holy Imam Hussain but Hussain refused to submit and stood by his values even in the advent of death.
In such circumstances, Hussain had to retire to Medina where he led a secluded life. Even here he was not permitted to live in harmony and had to look for asylum in Mecca. Yezid plotted to persecute him in this holy sanctuary as well and thus Hussain had to leave Mecca and proceed to Kufa. Thus in Karbala, Hussain and his companions sacrificed themselves in the name of God to show their stand against injustice and cruelty.
