In the name of God, Most Beneficent, Most Merciful
All praise belongs to God. He does what he wishes. No one can object Him. He does not require anybody’s suggestion. He is not bound by anyone. He is not afraid of anyone. Indeed, all praises belongs to God who dominates all and no one can ever dominate Him.
There are several signs that would exactly tell us the when Imam Mahdi would emerge that includes total domination of Israel in the world, Sea of Galilee getting dry and the most siginifcant sign is the total destruction of Army that will come to attack from Syria.
The Holy Prophet Muhammad (SAW) has prophesied about several events that will occur just before the advent of the day of judgment. Among these, Rasulullah(SAW) has foretold the advent of one of his descendants, Al Mahdi (the guided one), which will materialize when the believers are severely oppressed in every corner of the world. He will fight the oppressors, unite the Muslims, bring peace and justice to the world, rule over the Arabs, and lead a prayer in Mekkah at which Jesus (pbuh) will be present.
Here’s a Sunnah:
In hadith, it is narrated from Ibn Abbas(R.A.) that," Mahdi (A.S.) will appear at the time when people being upset would say that what for Mahdi (A.S.) would come now !! "
So practically, this is one of signs of the End of the World
