Umar bin Abd al-Aziz (may Allah have mercy on him) says that the last words of the Messenger of Allah (peace and blessings be upon him) were: "May Allah destroy the Jews and the Christians, who took the graves of the Prophets as places of prostration. Two religions shall not remain in the land of the Arabs."
