O, Imam Zaman (mgehr)! Peace upon you.

The most prominent slogan of Mahdism is “Justice”.

Justice is the loud voice of humans’ nature,

which has been deeply heard all over the world, and in the course of history.

Justice is the mystery of creation and stability of the universe.

And the world of creation has been based on it.

“The heavens and the earth were raised, based upon justice”

Justice, fairness and equation are the words that mean equality.

Therefore, Justice means to divide equally. And the narrations confirm it.

“The heavens and the earth were raised, based upon justice”

To spread justice and to fight against oppression and injustice, are at the forefront of goals for global revolution by the Promised Mahdī (mgehr).

The holy Prophet [Muḥammad (pbuh&h)] stated:

I give you glad tidings to [the emergence of] Mahdī (mgehr).

He will rise when people are engaged in oppositions, conflicts and riots.

And he will fill the world with Justice and equality; as it was once filled with oppression.
