Shiavault - a Vault of Shia Islamic Books Selected Narrations about the Twelfth Imam volume 2 Author’s Preface Those informed about Islamic history, traditions, and narrations are certainly aware of the abundance of glad tidings narrated from the Messenger of Allah, Allah's blessings be on him and his family, his holy progeny, peace be on them, and his companions regarding the reappearance of Imam Mahdī[^1], peace be on him, in the end of times (ākhir al-zamān) and the rise of the sun of his existence to dispel the darkness of ignorance, remove oppression and tyranny, spread the flags of justice, elevate the word of truth, and prevail over all religions even if the polytheists (mushrikīn) dislike it.
With the permission of Allah, he will free the world from the disgrace of worshipping anyone other than Allah.
(He will) set aside shameful habits and morals, put an end to defective laws formulated by humans in accordance with their desires, destroy all things that create enmity and hatred, break the bonds of all forms of prejudice—whether they be tribal, familial, national, or otherwise—which lead to differences in the nation, create separations, and inflame the fires of civil unrest and disputes.
Through his reappearance, Allah will fulfill His Promise which He has pledged in His sayings: Allah has promised those of you who believe and do good that He will most certainly make them successors on earth just as He made successors those before them, and that He will most certainly establish for them their religion which He has approved for them, and He will most certainly, after their fear, give them security in exchange.[^2] And We desired to bestow a favor upon those who were deemed weak on earth, and to make them the leaders, and to make them the heirs.[^3] Soon, the golden era will arrive during which no house will remain on the face of earth, but that in which Allah will enter the word of Islam and no village will exist, but that in which the testimony of there is no god except Allah will be called out every morning and evening.
Perhaps, some may claim that there exists no consensus amongst the Muslims on the issue (of the Mahdī) and their agreement on it is mere speculation.
