Imam Mahdi (A.S): The Last Luminary
part 2
Beside Quran, the sayings of the Prophet (PBUH) 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) 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)."
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. But there is no futility in creation.
In other words, ever since he has inhabited the earth, human has had the wish to lead a social life filled with happiness in its true sense and has striven toward this end. If such a wish were not to have an objective existence it would never have been imprinted upon human's inner nature, in the same way that if there were no food there would have been no meaning for hunger (since hunger is understood when one compares a person who has eaten food and a person who has not), and if there were no water there would have been no thirst and if there were no reproduction there would have been no sexual attraction between the sexes.
