— Imam Ali (P), The first successor of the Prophet Muhammad (P)[according to Shia Muslims]:
When the savior [ Mahdi] rises:
the sky will send down its drops ,
the earth will grow its plants,
enmity will come out from the servants’ hearts
and savages and beasts will continue to live together peacefully.
— Prophet Muhammad (P):
I promise you the advent of Mahdi (P) [the savior]; he fills the earth with justice as it is filled with oppressions and injustice; habitants of heavens and the earth will be satisfied from him and divides the properties and assets in correct way.
— Imam Reza (P), the grandson of the Prophet Muhammad (P):
the savior [ Mahdi] for the people:
is more deserving (to decide for them)

O Mahdi (P)! O great universal peacemaker!
The day that:
Dark clouds of tyranny and corruption cover the sky worldwide.
The day that:
The evil forces that would devour the world sink their claws even deeper into the throats of suffering people of the world.
The day that:
All principles are hidden from people’s minds when they weigh their thoughts, other than the principles of materialism and hedonism.
The day that:
Powerful waves of propaganda of the tyrants of the east and the west, present the Truth as false, and make falsehood seem to be the Truth, to secure their own illegitimate ends.
And finally the day that:
The lash of unkindness, narrow-mindedness, segregation, prejudice, illiberalities, envies, separations, discriminations, and oppression strike; injuring the backs of the vulnerable people of the world.
Yes!
At that moment, our hopeful eyes are turned toward you, great universal peacemaker.
To your universal revolution and government!
