Narrated by Anas bin Malik
The Prophet said, "There will be no town which Ad-Dajjal will not enter except Mecca and Medina, and there will be no entrance (road) (of both Mecca and Medina) but the angels will be standing in rows guarding it against him, and then Medina will shake with its inhabitants thrice and Allah will expel all the nonbelievers and the hypocrites from it."
Now with that above shown, take a look at this hadith and remember it as it is relevant to the topic:
I have five names, I am Muhammad, I am Ahmad, I am
al-Mahi (The eraser) with whom Allah erases blasphemy, I am
al-Hashir whom people will be assembled after, and I am
^Aqib (the last of all of the prophets.”
The following hadith is daciif but it correlates with the two hadith above, in other words, it's relevant:
The Messenger of Allah SallAllahu alaihi wasallam once addressed the people saying: "The Day of Deliverance, what is the Day of Deliverance!" and repeating it thrice. He was asked: "What is the Day of Deliverance?" He said: "The Dajjal (The Imposter of the End of Time) will come, climb on top of Jabal Habshi, look at Madinah, and say to his Companions: Do you see this white palace? This is the mosque of Ahmad. Then he will approach Madinah only to find on each path an angel with drawn sword. He will reach the wasteland of Al-Jurf and make camp. Madinah will then shake thrice and no hypocrite man or woman, nor corrupt man or woman will fail to go out to join him. This is the Day of Deliverance!" (Ahadith about the signs of The Hour, Mustafa Al-Adawi)
Now the traditional boundaries of the medinatul munawarrah is this:
While today Medina has expanded beyond this and deep into the outskirts of medina
The red circle in the image is Jabal Xabshi, Jabal Xabshi is 7km from the prophet's mosque.
Now what is this palace I'm talking about?, Interestingly, the Saudi's, intentionally or unintentionally have decided to build a complex large infrastructure 'palace' at the top of Jabal Xabshi, and calling it " The Kingdom's Palace". Pilgrims to Medina from around the world have said that the locals refer it to "Dajjal's palace". Here is the building:
For whatever the reason why this is being built, it is being built on a significant site.
Take a look at the line of sight between Jabal Xabshi, and the mosque of the prophet, despite 7km apart, ontop of jabal xabshi you can directly see the mosque of the prophet and it's minarets, thus verifying that dajjal will stand there and point towards the mosque saying " That white palace is the palace of Ahmad".
The circled red in the image is the mosque of the prophet, ofcourse in which at night and in person on the jabal habshi, you will be able to spot it because of it's bright white lights that shine in the dark.
