Why did Imam Hussain (PBUH) rise up ?
Imam Hussain's movement is , indeed , perceivable via two perspectives.
One perspective involves the appearance of Imam Hussain ’s action , which is a movement against a corrupt , deviated , suppressive and oppressive regime : Yazid ’s Regime .
But , at the heart of his action , there is a more important movement that the second perspective will lead to : the move against ignorance and humiliation of the mankind .
In fact , even though Imam Hussain fights against Yazid , his extensive historical fight is not against the short - living and insignificant Yazid . Rather , his main fight is against mankind ’s ignorance , abasement , deviation and humiliation . Ayatollah Khamenei
