A survey on the possibility of timing for the Advent

In this paper, timing for the Advent has been studied from two perspectives:One is that the Advent, as a social matter is a time phenomenon , whether it is a definite time or an indefinite and variable one; Another perspective refers to understanding the Advent time and, secondly, can the time of Appearance be achieved? Objectively , the answer to this question is positive, and subjectively, through the analytical and library method, the traditions in this field were first searched, twenty-one narrations were extracted and classified into five categories.
The result, according to the narrations was that, firstly, understanding the exact time of Advent is impossible, secondly, timing for the Advent, true or false, is not prohibited in itself; but its prohibition is due to attributing lies to the Ahlul-Bayt for personal interests.In the end, two questions about Gate narrations have also been addressed according to which the impossibility of achieving the time of Advent is due to the general scheme of Allah Almighty and the appointing a time by Ahlul-Bayt also refers to the past times, moreover, there is no information about their tone in this regard.
