All the duties that Muslims are charged with are undertaken by Hazrat Mahdi (a.t.f.s.) in their highest forms. He fulfils the best of it, and personally performs whatever he invites others towards it. In Islam, a deed performed by one for another is not accepted. Rather, every Muslim has an independent and separate duty, aside from few exclusive duties borne by the holy prophet and Imams.
The level and work of anyone depends on his responsibility, ability and duty. Imam-e-Zaman’s exclusive responsibility is to implement the Islamic ordinances all over the earth; uproot tyranny and oppression from the earth and hoist the banner of Islam and monotheism in every nook and corner of the earth. All the Muslims bear this responsibility but their global leader in this affair is Imam-e-Asr (a.t.f.s.) who would lead them. As such, the common duty of the Muslims doesn’t in any way contradict the global duty of Hazrat Mahdi (a.t.f.s.) as an Imam, leader and commander. The same is true to all the other qualities we attribute to him in Dua’e-Nudba . For example:
“Where is the awaited one, for the correction of the bent and crooked….?”
“Where is the object of hope for demolishing tyranny and hostility?”
“Where is the one safely stored-up for the revival of precepts and ordinances?”
In all these expressions, Imam Hujjat-ibn’l-Hasan (a.t.f.s.) is looked upon as a leader and guide. Such remark exists in all cultures where the work of one executing the command is ascribed to the commander too because he bears the responsibility of drawing the plan, managing its implementation and harmonizing the forces.
