Dear teacher, when His Eminence Ali (AS) was martyred, the person responsible was immediately subjected to retribution. In the tragedy of Ashura, too, those responsible for the martyrdom were subjected to retribution by Mukhtar.
But what of the other infallible Imams who were martyred by unjust caliphs? Why did those responsible for their martyrdom not face the consequences of their actions in this world?
Did Mukhtar Avenge the Martyrs of Karbala?
The essence and first answer at a glance (60-word summary)
The vengeance for our master, Amir al-Mu’minin, and for His Eminence Sayyid al-Shuhada and the martyrs has not yet been exacted. Rather, the Almighty Creator will exact it through His own power. The worthless lives of men such as Ibn Muljam, Shimr, and Harmala are no recompense for the blessed lives of these noble figures. God, All-Knowing and All-Wise, knows how to exact vengeance on their behalf. Mukhtar’s vengeance was simply a worldly punishment for the killers.

Teacher and researcher in the intellectual tradition of wisdom and the Ahl al-Bayt | Soroush Bamdadān Cultural CenterThe vengeance for the Master of the Believers, peace be upon him, for His Holiness the Prince of Martyrs, peace be upon him, and for the martyrs has not yet been exacted. Yet the blood of the Infallibles, peace be upon them, is a claim upon the Lord, the Exalted, and He will exact their vengeance by His own power; and Allah is well aware of how to take vengeance. Retribution must be equal, whereas the worthless lives of the likes of Ibn Muljam, Shimr and Harmala are no match for the blessed lives of Their Holinesses; and "the All-Knowing, All-Wise, Avenging and Just God" knows how to exact vengeance for them. One must be patient and bear witness.
The vengeance taken by the esteemed Mukhtar, may God have mercy on him, was merely a worldly punishment for the murderers.
