Contradictory ideas will emerge regarding the coming of Hazrat Mahdi (as) in the end times

They will imagine that his [Hazrat Mahdi’s (as)] coming is a wish, a rumor. But the fact is that Hazrat Mahdi (as) will be a reality.

(Bihar al-Anwar, Vol. 13, p. 909)

In the End Times, some people will be skeptical with regard to the coming of Hazrat Mahdi (as). They will think that Hazrat Mahdi (as) will never come. But Hazrat Mahdi (as) will appear, insha’Allah, at a time ordained by Allah.
