It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: I give you the glad tidings of Mahdi, who will appear in my Ummah at a time when there will be many differences and earthquakes, and he will fill the earth with justice and fairness just as it was previously filled with oppression and injustice. The inhabitants of the heavens will be pleased with him, and so will the inhabitants of the earth. He will distribute wealth correctly. Someone asked, "What is meant by distributing wealth correctly?" He replied, "He will distribute it equally among the people." And in his time, Allah will fill the hearts of the Ummah of Muhammad with contentment, and He will grant them abundance through his justice, to the extent that he will order a caller, and the caller will announce that whoever is in need of wealth should come to us. Only one man will come to him and say, "I am in need." He will say to him, "Go to the treasurer and tell him that Mahdi orders you to give me wealth." The treasurer, according to the order, will say to him, "Take as much as you can with your own hands." When he wraps it up in a cloth and ties it, he will feel ashamed and say to himself, "I am the greediest among the Ummah of Muhammad; did I not have as much as the others had?" Thinking this, he will return all the wealth, but it will not be accepted back from him, and he will be told, "We do not take back what we have given." This situation will remain for seven, or eight, or nine years, after which there will be no benefit in living.
