Medina is the first capital of the Prophet's rule. It is stated in history that the Jews first came to Yathrib and founded this city. They settled in this area en masse long before the birth of the Prophet. The Jews had heard that the Prophet of the End Times would come to Yathrib and had complete information about it.
They claim that they came to Medina to find the Prophet of the End Times and believe in him, but by examining the course of history, we doubt the veracity of this statement. If so, why did they not believe in Jesus (peace be upon him), who showed many miracles? In addition, it is worth asking why the Jews, who knew that the Prophet of the End Times would be sent to Mecca, did not come to Mecca? Why did they settle in an area that was uninhabited? The Jews knew that the Prophet of Islam (peace be upon him) would be established between the two mountains of Ir and Uhud, and therefore they settled in this area. Here the question arises, why did the Jews disperse in the land of Hijaz when the area between these two mountains is a limited area?
They claim that they made a mistake in finding the location of this area, so some settled in Khaybar, some in Tabuk, and some in other areas. But this claim is nothing more than a lie, because by looking at the map of these areas, we realize that these areas are right on the road from Medina to Jerusalem. By settling in these areas, they easily blocked the Prophet's path to Jerusalem. If the Prophet wanted to go from Medina to the land of Canaan (Palestine), the Jews would be against him. If he passed through Iraq, he would reach Fadak, and if he passed through Medina, he would reach Khaybar. How can we accept that they settled in his capital by chance and accident!?
The Prophet had been in Mecca for thirteen years, and the Jews were aware of his mission; even one of the Jewish scholars, on the day of the Prophet's birth, identified him. How could the Jews of Medina not know that the Promised Prophet was born in Mecca? If they came to Medina to help the Prophet of the End Times, why did they not believe in him in Mecca even though they knew him well? Long before the birth of the Prophet (PBUH), Hashim said to his wife while passing through Medina: If the Jews find this child (Abdul-Muttalib), they will kill him. This was the time when the Jews were saying to the people of Medina: This Prophet is for us and we have believed in him.
Thus, we find that the Jews came to Medina and its surroundings to prevent the Prophet (PBUH) from entering Jerusalem. Looking at the map of the Jewish settlement in the Hijaz, it is easy to see that the Jews built an embankment from Medina to the walls of Jerusalem. They had provided extraordinary military fortifications and huge obstacles on this path. The Prophet had to overcome seven obstacles to reach Jerusalem. Ibn Yaqridah, Banu Mustaliq, Ibn Yandir, Khaybar, Tabuk, Mutah and Jerusalem. The first three embankments were in Medina and the Jews stationed there, each at a specific time, fought the Messenger of God (PBUH). In the subsequent obstacles, the Prophet advanced to Mutah in various battles, but due to the cunning of the Jews, he did not reach Jerusalem.
God entrusted the mission of conquering Jerusalem to the Al-Muwahhids. (Old Testament, Chapter 26) That is why the Prophet of Islam moved towards Jerusalem. According to Jewish sources, if the Prophet of the End Times seizes or settles in a land, he will not lose it again, and therefore, if the Prophet of Islam reaches Jerusalem, the Jews must abandon the global movement; for this reason, the Jewish barriers and strongholds of Banu Qaynuqa, Banu Qurayza, Khaybar, etc. were established in Medina to Jerusalem.
These fortifications were built over many years. The fortifications of Khaybar dug a ditch on the mountain, built a wall on the ditch, and built a castle on the other side of the wall, while they had no enemies in Medina. Therefore, we understand that they had already planned a heavy defense against the Prophet of the End Times. In practice, we saw that they made the most of these castles in the war with the Prophet, then delayed the Prophet (PBUH) in Tabuk. The result of these efforts was the defeat of the Prophet (PBUH) in the last battle at Mu'tah.
Usama's army was the last force that the Prophet equipped to move towards the borders of Rome and modern Palestine. However, with the death of the Prophet (PBUH) and the sabotage of well-known individuals in history, this army stopped moving, and unfortunately, the Jewish delaying operation was able to prevent the Prophet (PBUH) from reaching Jerusalem.
