There can be no Islamic Union without the way of the Mahdi. Islamic countries will not unite. Shiite Iran will not accept a Sunni leader. Neither will a Sunni country accept Shiite leadership. And there can be no Islamic Union under such circumstances. But Shiites will also accept Hazrat Mahdi (as), and Sunnis, and Alawites, and Bektashis and Wahabbists. Christians will also accept him, and Jews. Because Christians and Jews are awaiting Hazrat Mahdi (as). - Harun Yahya
