The Jews are hated in the Arab nations because both the Jews and the Arabs have the same ancestor - whom they call Father Abraham.
Abraham had two children (Ishmael and Isaac) by two different wives.
Ishmael became the forefather of the Arabs.
And Isaac became the forefather of the Jews.
In other words - Arabs and Jews are half-brothers!
Who believe they are the children of the promise of God to inhabit the nations. And Israel is the place they both believe belongs to them!
Many Arabs are Muslims and their philosophy is to conquer the world because of their understanding of this promise to inhabit the nations.
Isaac, the progenitor of the Jews, was the legitimate son of his wife Sarai; while Ishmael, the progenitor of the Arabs, was the illegitimate son of his concubine, Hagar.
