Hadith Describing How in the Time of Hazrat Mahdi (as) No Blood Will Be Spilled and How Even the Sleeper Will Not Be Wakened

People will seek refuge in Hazrat Mahdi (as) as honey bees cluster around their sovereign. He will fill the world that was once full of cruelty, with justice. His justice will be as such that HE WILL NOT WAKE A SLEEPING PERSON OR EVEN SHED ONE DROP OF BLOOD. The Earth will return to the age of happiness.1

[Hazrat Mahdi (as)] will follow the way of the Prophet. HE WILL NOT WAKE UP A SLEEPING PERSON OR SHED BLOOD.2

HAZRAT MAHDI (AS) WILL BE SO COMPASSIONATE THAT NO ONE WILL BE WOKEN UP FROM THEIR SLEEP OR HAVE A BLEEDING NOSE.3

Those who swear allegiance to him [Hazrat Mahdi (as)] will swear between the rock and the pillar (by the Kaaba). HE WILL NOT WAKEN THE SLEEPER, AND HE WILL SPILL NO BLOOD.4

In the time of Hazrat Mahdi (as), WAR WILL COME TO AN END AND ARMIES WILL ABANDON THEIR WEAPONS AND EQUIPMENT:

War will lay down its burden (arms and the like).5

The warriors will abandon their weight [weapons and kits].6

All grudges and mutual hatred will be lifted (removed)... Earth will be filled with peace, just as a vessel is filled with water; the word will become one [i.e., there will be only one religion], and only Allah will be worshiped; the battle will put down its weapons [i.e., come to an end].7

In the time of Hazrat Mahdi (as), ENMITY, CONFLICT AND WAR WILL COME TO AN END.

There will be no enmity between anyone. And all enmity, quarrels and disputes will surely disappear.8

In the time of Hazrat Mahdi (as), THE WORLD WILL BE FILLED WITH JUSTICE:

HE [HAZRAT MAHDI (AS)] WILL FILL THE WORLD, once filled with oppression, WITH JUSTICE instead.9

The Mahdi is one of my people, and HE WILL FILL THE EARTH WITH TRUTH AND JUSTICE, just as it was once filled with cruelty and torture.10

In the time of Hazrat Mahdi (as), THE WORLD WILL BE FILLED WITH PEACE:

[In Hazrat Mahdi's (as) time] ALL GRUDGES AND MUTUAL HATRED WILL BE LIFTED (REMOVED), the sting of every stinging insect will be removed until a baby will insert his or her finger in snake's mouth and not be harmed, and the wolf will be like the dog among the sheep [safeguarding them]. EARTH WILL BE FILLED WITH PEACE, just as a vessel is filled with water; the word will become one [i.e., there will be only one religion], and only Allah will be worshiped; the battle will put down its weapons [i.e., come to an end].11

... In his [Hazrat Mahdi's (as)] day the sheep will graze with the wolf, and children will play with snakes...12
