To answer you,Ever since King David made Jerusalem the capital of Israel more than 3,000 years ago, the city has played a central role in Jewish existence. The Western Wall in the Old City — the last remaining wall of the ancient Jewish Temple, the holiest site in Judaism — is the object of Jewish veneration and the focus of Jewish prayer. Three times a day, for thousands of years, Jews have prayed "To Jerusalem, thy city, shall we return with joy," and have repeated the Psalmist's oath: "If I forget thee, O Jerusalem, let my right hand forget her cunning."
Jerusalem "has known only two periods of true greatness, and these have been separated by 2,000 years. Greatness has only happened under Jewish rule," Leon and Jill Uris wrote in Jerusalem. "This is so because the Jews have loved her the most, and have remained constant in that love throughout the centuries of their dispersion....It is the longest, deepest love affair in history.For three thousand years, Jerusalem has been the center of Jewish hope and longing. No other city has played such a dominant role in the history, culture, religion and consciousness of a people as has Jerusalem in the life of Jewry and Judaism. Throughout centuries of exile, Jerusalem remained alive in the hearts of Jews everywhere as the focal point of Jewish history, the symbol of ancient glory, spiritual fulfillment and modern renewal. This heart and soul of the Jewish people engenders the thought that if you want one simple word to symbolize all of Jewish history, that word would be 'Jerusalem.'” Jews have been living in Jerusalem continuously for nearly two millennia. They have constituted the largest single group of inhabitants there since the 1840's (map of Jerusalem in 1912) .Jerusalem contains the Western Wall of the Temple Mount, the holiest site in Judaism.
Jerusalem was never the capital of any Arab entity. In fact, it was a backwater for most of Arab history. Jerusalem never served as a provincial capital under Muslim rule nor was it ever a Muslim cultural center. For Jews, the entire city is sacred, but Muslims revere a site — the Dome of the Rock — not the city. "To a Muslim," observed British writer Christopher Sykes, "there is a profound difference between Jerusalem and Mecca or Medina. The latter are holy places containing holy sites." Besides the Dome of the Rock, he noted, Jerusalem has no major Islamic significance
