Today, the Islamic claim to Palestine (the Promised Land) and to Jerusalem comes from their misunderstanding of the Abrahamic Covenant. Tragically, Muslims take God's covenant promise of land and blessing to apply to Ishmael and not Isaac, in contradiction to Gen -21! They believe that Ishmael, not Isaac, was the son whom Abraham nearly sacrificed, and that Ishmael was the son of promise. This is despite the fact that Jerusalem is mentioned more than 700 times in the Bible, but not once in the Quran! So, for example, Jordan, driven by Islamic ideology, joined four other Arab armies in 1948-49 in a war against the new State of Israel, and took by force East Jerusalem and the West Bank (Judea and Samaria).
