Umar Iban Al-Khattab, re-opened Jerusalem to Jews and allowed them to return
When exactly had they left and why did they leave and where did they go? I would like to remind you that they have not found a single Jew anywhere on this planet who has a genetic link to Palestine – none – and also keep in mind that 95% of the Jews of the world are the Ashkenazi who according to their own DNA are 100% European and therefore completely foreign to the Middle East.
