In the same section and the same chapter of the afore-said book, the author narrates from Ali-ibn- Abi Talib as such: There is no heresy but that Mahdi will eradicate it and there is no 'Sunnah' (practice) too but that Mahdi will establish it...
In the third chapter of the afore-mentioned book, he narrates from Abu Bakr Baihaqi (from the book "Besath-wa-Nushur"), Ahmad-ibn-Hemad (from the book 'Mustadrik') and Abu Na'eem (from the book "Sefat-ul-Mahdi") who all narrate from Abu Sa'eed Khudri that the Messenger of Allah (S.A.W.A.) said: I give you glad-tidings about Mahdi. He will emerge amongst my nation at the time when they will be in discord and war with each other.
Then, Hazrat will fill the earth with equity and justice just as it was fraught with tyranny and oppression... Mahdi will fill the hearts of Muhammad's nation with riches and make them free from want. His justice would embrace all of them... In the seventh chapter of the afore-mentioned book, he narrates from Amir-ul- Mumineen Ali (A.S.) as such: Mahdi will despatch his chiefs to various cities for establishing justice amongst the people. The wolves and sheeps shall graze together.
The children will play with the snakes and scorpions without being harmed the least. Evil will vanish and goodness will remain. People will cultivate about 750 grammes and will receive in return about 525 kilograms just as the same has been mentioned in the Holy Quran. Adultery, wine - drinking and usury will be uprooted. People will have a relish for worship, divine laws and faith and a desire for mixing in the society.
Life of man will lengthen, properties held in trust would be returned back, trees will bear fruits, blessings will double, the wicked will be destroyed, the virtuous ones will remain and those having grudge against the Ahl-e-Bayt will cease to exist.
In the third chapter of the afore-said book, the author narrates from Nae'em- ibn-Hemad (from the book "Fatan") who in turn narrates from Jafar-ibn-Bashar Shami that (during Mahdi's era) injustice would be rebuffed to such extent that if something belonging to someone is hidden under a person's tooth he would remove it and give it back to its owners.
