How will the Dajjal come to a valley in Medina if he will not enter it?

Numerous authentic hadiths state that the Dajjal will not enter Medina, and that Allah Almighty will place angels at its gates to guard it. As for the hadith mentioned by the questioner regarding the Dajjal's entry into Medina, its chain of transmission is weak. Even if it were authentic, it does not contradict other hadiths, as it merely indicates his passage through a salty, barren land outside Medina, not within it, specifically "Sabkhat al-Jurf." Therefore, the Dajjal will not enter Medina, but will only reach the saline lands adjacent to it. And Allah knows best.
