By studying these matters and tens of other similar indications, it is deduced that the Islamic message will reach its complete fulfillment when these holy aspirations will take place. All fabricated and superstitious objectives will disappear and then only the Islam, the unique and true religion, will be the faith of the people in the east and west of the world.
Injustice, oppression, and inequality shall vanish, and instead, justice and equality which is the law of the creation of the world will be established everywhere. The Kingdom of the divinely appointed Caliph (Khalifatullah) will manifest itself in all the corners of the world. The light of the guidance of Allah will shine and the earth shall belong to the virtuous ones. Yes, Quran gives the Good News which the day that all Muslims of the world are enthusiastically waiting for it, will arrive.
Beside Quran, the sayings of the Prophet (PBUH&HF) are the most important and worthiest treasure of Islamic learning. In the sea of jewels of Islamic traditions glad tidings on the Government of Justice can be seen which is regarding to the "Divine Revolution" and the "divinely appointed leader" who will fulfill this holy aspiration.
In a tradition upon whose authenticity all Muslims agree, the Messenger of Allah (PBUH&HF) has said: "Even if the entire duration of the world's existence has already been exhausted and only one day is left before Doomsday, Allah will expand that day to such length of time as to accommodate the kingdom of a person from my Ahlul-Bayt who will be called by my name.
He will fill out the earth with peace and justice as it will have been full of injustice and tyranny (by then)." [Please see the next article for the list of Sunni references for the above tradition as well as many other traditions.] The above precious tradition testifies that the golden divine promises will take place, sooner or later, one way or another, as also mentioned in most of the Shi'ite and Sunnite sources.
In both subjects of prophecy and Imamat (leadership) it is discussed that as a result of the law of general guidance which governs all of creation, human is of necessity endowed with the power of receiving revelation through prophecy, which directs him toward the perfection of the human norm and the well-being of the human species. Obviously, if this perfection and happiness were not possible for human, the very fact that he is endowed with this power would have been meaningless and futile.
