#ArrivalOfLastSaviourMEHDI HERE'S WHAT YOU NEED TO KNOW ABOUT IMAM MAHDI

Hazrat Umm-e-Salma states that Hazrat Muhammad (P.B.U.H) said: 

“After the death of a Ruler, there will be some dispute between the people. At that time a citizen of Madina will flee (from Madina) and go to Makkah. While in Makkah, certain people will approach him between Hajrul Aswad and Maqaame Ibraheem, and forcefully pledge their allegiance to him.
Thereafter a huge army will proceed from Syria to attack him but when they will be at Baida, which is between Makkah and Madina, they will be swallowed into the ground.”

THIS WILL BE THE BIGGEST SIGN OF APPEARANCE OF IMAM MEHDI

There are two beliefs one of SHIA and one of SUNNI. 
 Here we’ll be stating about both the beliefs:
According to SHIA’S: He is their 12th Imam, They believe that Imam Mehdi has already been born and is in a cave from the last 1200 years and will come out in the end.  

Sunni’s believe that: He will be born like a normal human being. He will live like a normal human being. He will be fond of gaining knowledge. His full name will be Muhammad Bin Abdullah or Ahmed bin Abdullah.

Muhammad (P.B.U.H)said:  

“A time will come when there will be brutality and injustice everywhere, Allah will send Imam Mehdi. Imam Mehdi will be from the family of Hazrat Muhammad (P.B.U.H) and will be just like any other human but will be bestowed with knowledge and better character in one night.
 

Prophet Muhammad (P.B.U.H) said: 

“Allah will bring up a man from my family whose name will be on my name, his father’s name will be on my father’s name and mother’s name on my mother’s name. He will bring peace in the land of ARAB”

In another reference he said: 

“Mehdi will be from my family will have a bright forehead and a straight nose. He will fill the land with peace as it would be filled with injustice and brutality and he will rule for 7 years.”
