The reason why we want [the appearance of] Hazrat Mahdi (pbuh) is the Unity of Islam. They are the same; no difference in wanting the Unity of Islam or [the appearance of] Hazrat Mahdi (pbuh). The abbreviated name for the Unity of Islam is the system of the Mahdi. The extended form of the system of the Mahdi is the Unity of Islam. Those who want the Unity of Islam would in any case want [the appearance of] the Mahdi. Those who want the [appearance of] would want the Unity of Islam as well. There is no meaning in making any kind of differentiation in this. And we see the Unity of Islam in the whole of the Qur'an. It is the command of Allah. The Unity of Islam is a religious obligation, it is the greatest religious obligation.
