ADNAN OKTAR: "Mr. Oktar, will Istanbul be the administrative capital in the era of Hazrat Mahdi (pbuh)? Will the Prophet Jesus (pbuh) be a governor or a religious leader? Will the Buddhists, Chinese and Indian people convert to Islam? How many years will it take for these two and a half billion people to convert to Islam? With my sincere regards and compliments." Esra. Let me tell you, Istanbul has always been the capital of the whole world. Istanbul is Rome. It is the Rome of the world and always will be. It was named as 'Rome', named as 'Constantinople'. You should know that Istanbul is the Rome of the world and will remain so until the Last Day. Wasn't it the capital of the Roman Empire? The end of discussion. It will always remain so. Wasn't it the capital of the world of Islam? The end of discussion. These spiritual titles are eternal. Our Prophet (pbuh) informs us that the Prophet Jesus (pbuh) will appear as the vizier of Hazrat Mahdi (pbuh). Alm
