The translation of the hadith:
(…) When Messiah (The prophet Isa) would lower his head, there would fall beads of perspiration from his head, and when he would raise it up, beads like pearls would scatter from it. Every non-believer who would smell the odor of his self would die and his breath would reach as far as he would be able to see. He would then search for him (Dajjal) until he would catch hold of him at the gate of Ludd and would kill him. Then a people whom Allah had protected would come to Jesus, son of Mary, and he would wipe their faces and would inform them of their ranks in Paradise and it would be under such conditions that Allah would reveal to Jesus these words: I have brought forth from amongst My servants such people against whom none would be able to fight; you take these people safely to Tur. And then Allah would send Gog and Magog and they would swarm down from every slope. The first of them would pass the lake of Tiberias and drink out of it.
(Sahih Muslim 2937 a)
I explained it earlier. The meaning of the word “breath” in these hadiths is the metaphysical abilities. The prophets and the high-ranking walis can even shake the continents by saying Huuu when breathing out.
They can even kill millions of people in another planets suddenly and collectively.
“The breath” is mentioned in the hadith about how Hz. Mahdi and the prophet Isa will kill Dajjal. They will kill him from distance with metaphysics.
Quds which is mentioned in these hadiths is actually Istanbul…
The Mount Sinai is an artificial mountain. It is a spaceship with very advanced technology. Even the Gog and Magog who are the Greens and the Grays don’t have the technology it has. The Greens and Grays don’t have this technological level in their own planets. They will come to the world, they will eliminate the herd who cannot be called the nation all around the world, simultaneously. The prophet Isa, Hz. Mahdi and a small number of believers will be in the Mount Sinai and will be protected. The Greens and Grays will not be able to damage the Mount Sinai.
Thus, Hz. Mahdi will experience an event very similar to the biggest/most shocking event the prophet Noah experienced. As I always said, Hz. Mahdi will experience events very similar to the great events all the great prophets experienced. He will be tested by the events the great prophets was tested and he will pass all of them.
