Answers to some questions
Is It Not Possible that the Mahdl' Has Already Appeared?
HOW WILL THE CHANGE ON THE APPOINTED DAY OCCUR?
How can we can form an image about what will be accomplished at the hands of this individual in terms of a decisive victory for justice and an end to the existence of transgression that he is faced with?
The limited answer for this question is related to the knowledge of the time and the phase in which al-Mahdi (peace be upon him) is supposed to emerge to the world, as well as the possible assumption regarding what peculiarities and close relations, might characterize that phase so as to be able to draw, in that light, the shape that the operation of change would take and the path that it would follow.
But as long as we do not know anything concerning that phase, its environment nor its circumstances, we cannot scientifically predict what would take place on the appointed day, although we can imagine or give certain assumptions in this respect, which are founded on theoretical bases and not on realistic grounds.
There is one basic assumption which we can adopt in the light of the previous narratives we mentioned earlier, as well as in the light of the great operations of change in the course of history, namely the appearance of al-Mahdi (peace be upon him) after a great gap which will result in a shocking decadence and a crisis is civilization. This
gap will give the opportunity for the message to expand
and the decadence of civilization will prepare the
psychological atmosphere for its acceptance.
However, this decadence in civilization is not a mere incident that will occur suddenly in the history of human civilization, but a natural result of a contradiction in history that is cut off from Allah, the Exalted, that cannot reach a decisive solution of the end of its course, so that its fire will burn leaving nothing in its path and the light will then appear to establish a Divine justice on earth.
