Justice and Blessings During the Reign of the Mahdi (radhiyallahu ‘anhu)
The reign of the Mahdi (radhiyallahu ‘anhu) will be one of justice and barakah (blessings). Since the Mahdi (radhiyallahu ‘anhu) will be divinely chosen by Allah Ta‘ala to lead the ummah before Qiyaamah, he will be divinely guided and supported by Allah Ta‘ala. Hence, every decision that he will pass will be filled with goodness and justice. During his rule, Allah Ta‘ala will bless the Muslims with abundant barakah (blessings) and will restore the might and honour of Islam in the ummah.
Rasulullah (sallallahu ‘alaihi wasallam) said, “The Mahdi (radhiyallahu ‘anhu) will appear in the latter portion of my ummah. Allah Ta‘ala will grant him abundant barakah through causing abundant rain to fall from the sky, due to which the earth will bring forth abundant crop. He will distribute wealth justly among the Muslims, the livestock will increase and be found in abundance and the ummah will once again regain its might and honour. After being appointed by Allah Ta‘ala, he will live for seven or eight years.” (Mustadrak Haakim #8673)
The Extent of Justice and Contentment during the Reign of the Mahdi (radhiyallahu ‘anhu)
In some Ahaadith, it is recorded that the Mahdi (radhiyallahu ‘anhu) will rule with such justice and fairness that the inhabitants of the earth and the heavens will be pleased with him, and wherever he goes in the world, Allah Ta‘ala will cause goodness and barakah to prevail. His justice will encompass all the people and he will deal with them according to the Sunnah of Rasulullah (sallallahu ‘alaihi wasallam).
On account of his justice, when he will instruct a person to announce, “The one who has a need should come to me,” only one person will come (as the needs of all the other people will have been fulfilled due to his just rule).
Hazrat Abu Sa’eed Khudri (radhiyallahu ‘anhu) reports that once, Rasulullah (sallallahu ‘alaihi wasallam) addressed the Sahaabah (radhiyallahu ‘anhum) saying, “I give you glad tidings of the Mahdi (radhiyallahu ‘anhu) coming to this ummah (before Qiyaamah)! He will be sent to this ummah at a time when differences among the ummah will be rife and earthquakes will be witnessed in the world. He will rule in such a manner that the earth will be filled with fairness and justice, just as it was previously filled with oppression and tyranny. The inhabitants of the sky and the inhabitants of the earth will be pleased with him. He will distribute wealth correctly.”
A Sahaabi (radhiyallahu ‘anhu) then asked Rasulullah (sallallahu ‘alaihi wasallam), “O Rasul of Allah (sallallahu ‘alaihi wasallam)! What is the meaning of the Mahdi (radhiyallahu ‘anhu) distributing wealth correctly?” Rasulullah (sallallahu ‘alaihi wasallam) replied, “It means that he will distribute wealth with equality and justice between the people.”
Rasulullah (sallallahu ‘alaihi wasallam) then continued, “At that time, Allah Ta‘ala will fill the hearts of the ummah of Muhammad (sallallahu ‘alaihi wasallam) with contentment and happiness. The Mahdi’s (radhiyallahu ‘anhu) rule of justice will encompass the people, until people will enjoy great blessings through him, so much so that a person will address the people saying, ‘Which person among you is in need of wealth?’ From all the people, only one man will stand up and say, ‘I am in need of wealth!’
“The person will say to him, ‘Go to the treasurer and say to him, ‘The Mahdi has given instructions to you to give me wealth.’’ When he will come to the treasurer, the treasurer will say to him, ‘Take wealth in both your hands, as much as you wish!’ The man will thus take wealth with both his hands, gathering it before him.
“At that point, the man will regret and say, ‘I was the most desirous for wealth from the ummah of Muhammad (sallallahu ‘alaihi wasallam)! Can that which sufficed them not suffice me?’ Saying this, he will return the wealth. However, the wealth that he will wish to return to the Mahdi (radhiyallahu ‘anhu) will not be accepted from him, and he will be told, ‘That which we give, we do not take back.’
“This condition of barakah will continue to prevail throughout the period of the Mahdi which is either seven, eight or nine years.” (Majma’uz Zawaa’id #12393)
