Islam's predictions of the last days.
While the people will be pledging their allegiance to Imam Mahdi, a voice from the unseen will call out:
"This is the representative of Allah,
The Mahdi, listen to him and obey him"
This announcement which will be heard by all those present will establish his authenticity.
Hadhrat Abu Umamah (R.A.) says that Rasulullah (Prophet Muhammad) said: "There will be four peace agreements between you and the Romans (the Western powers). The fourth agreement will be mediated through a person who will be from the progeny of Hadhrat Aaron (that is will be from the priestly Levite tribe of Israel) (A.S.) and will be upheld for seven years."
The people asked: "O Rasulullah (Prophet Muhammad), who will be the Imam of the people at the time?"
Rasulullah (Prophet Muhammad) said: "He will be from my progeny and will be forty years of age. His face will shine like a star and he will have a black spot on his left cheek. He will don two "Qutwaani" cloaks and will appear exactly as a person from the Bani Israeel (Children of Israel)..." (Tabrani)
According to hadith narrated by Abu Saeed Khudri (R.A.) Rasulullah (Prophet Muhammad) said: "...(regarding the rule of Imam Mahdi) the skies will rain down in abundance and the earth will yield forth its crop in abundance, and those alive will desire that those who have already passed away should have been alive to enjoy this prosperity..."
Hadhrat Buraidah (R.A.) says that Rasulullah (Prophet Muhammad) said: "There will be many armies after me. You must join that army which will come from Khurasaan (Iran)." (Ibn Adi)
1) Abu Hurairah (R.A.) says that Rasulullah (Prophet Muhammad) said: "(Armies carrying) black flags will come from Khurasaan (Iran). No power will be able to stop them and they will finally reach Eela (Dome of the Rock in Jerusalem) where they will erect their flags."

2)The Prophet (PBUH and HF) said: "Even if the entire duration of the world's existence has already been exhausted and only one day is left (before the day of judgment), Allah will expand that day to such a length of time, as to accommodate the kingdom of a person from my Ahlul-Bayt (family) who will be called by my name. He will fill out the earth with peace and justice as it will have been full of injustice and tyranny (by then)."

4) The Prophet (PBUH and HF) said: "We (I and my family) are members of a household that Allah (SWT) has chosen for them the life of the Hereafter over the life of this world; and the members of my household (Ahlul-Bayt) shall suffer a great affliction and they shall be forcefully expelled from their homes after my death; then there will come people from the East (see above hadeeths that say this army will come from Khorasan modern day Iran) carrying black flags, and they will ask for some good to be given to them, but they shall be refused service; as such, they will wage war and emerge victorious, and will be offered that which they desired in the first place, but they will refuse to accept it till they pass it to a man from my family (Ahlul-Bayt) appears to fill the Earth with justice as it has been filled with corruption. So whoever reaches that (time) ought to come to them even if crawling on the ice/snow since among them is the Vice-regent of Allah (Khalifatullah) al-Mahdi."

5) Abu Nadra reported: We were with the company of Jabir Ibn Abdillah... Jabir Ibn Abdillah kept quite for a while and then reported Allah's Messenger (may peace be upon him) having said: "There would be a Caliph in the last (period) of my Ummah who would freely give handfuls of wealth to the people without counting it." I said to Abu Nadra and Abu al-Ala: Do you mean Umar Ibn Abd al-Aziz? They said: NO, (he would be Imam Mahdi).
