The son of the honest and the nobles will come

Imam Mahdi's mission to establish justice and equity is deeply connected to Imam Husayn's movement against injustice and humiliation by the oppressors. Before the advent of Imam Mahdi, almost everyone will know who Imam Husayn is and what he stood for;

those who struggle for justice would refer to him as their role model, and those who fight against them would question Imam Husayn and his followers, and finally they would support and show their disgus of what was committed by Yazid and his people and as a result associate themselves with the killing of Imam Husayn and his family members and companions.
