Dajjal is already around when Isa (as) descends to that mosque in the white minaret in Damascus. My understanding it will be during the Maghrib prayer that he will descend. The Mehdi is the one who will identify him and tell people that Isa (as) is with us. Isa (AS) will then seek Dajjal and meet him at the gate of Ludd. That is where the False Messiah (Dajjal) will perish at the hands of the True of Messiah (as). But make no mistake about it, there will be a big war that will have to happen during that time.
At this point, we still don't have the malhama (the Great war). We still don't have that blessed revolution in Hejaz where hypocrites will chase the Mehdi from Medina and where the people will come out Mecca and make ba'yah (pledge of allegiance) to him.
We still don't have the army from Shaam that will attack as soon as they hear the people are making pledge of allegiance to him. This army will be swallowed by the earth.
We still don't have the sun rising from the West.
What we have now is the Zionists/Freemasonries making so much mischief (massacres, ethnic cleansing, etc) for the imminent arrival of their "Jewish King" or "the Anointed One".
Joe Biden, Emmanuel Macron,
Rishi Sunak, Benjamin Netanyahu, and many others including leaders in the Arab and Muslim leaders are all Freemasonries.
