First of all to prove that the belief in Imam Mahdi (a.t.f.s.) is not restricted only to the Shias, Janab Muhaddise Noori(r.a.) mentions about numerous books written by famous scholars of Ahle Tasannun about Hazat Mahdi's (a.t.f.s.) existence.

Thus all Muslims believe that Hazrat Mahdi (atfs) will appear in the last period of time. He would be the namesake of the Holy Prophet (sawa). He will fill the earth with justice and equity as it would be previously filled with injustice and oppression.

He then discusses about some differences regarding his Holy personality.

The first difference is about some reports of his lineage. He puts forward convincing arguments rejecting these differences and establishes that Imam Mahdi (atfs) is the descendant of Imam Husain (as).

He narrates a tradition from the Holy Prophet (sawa) as follows:

"O Fatima, indeed we Ahle Bayt (a.s.) are bestowed with six qualities, which are not given to anyone of the formers and neither will anyone from the latters be given that except us, Ahle Bayt (a.s.).

Our prophet is the best of the prophets and he is your father.

Our successor is the best of the successors and he is your husband.

Our martyr is the best of the martyrs and he is Hamza, the uncle of your father.

From us are the two youths of this Ummah. And they are your two sons.

From us is the Mahdi of this Ummah, behind whom Prophet Isa (a.s.) will pray.

Then he tapped on the shoulders of Imam Husain (a.s.) and said:

From this one is the Mahdi of this Ummah.

May the Almighty hasten his reappearance and enumerate us amongst his followers.
