This book deals with the Muslim world’s need for the establishment of a Turkish Islamic Union and its importance for world peace in the light of the political, sociological and economic facts. The current situation clearly suggests that Muslims will influence the developments of the twenty-first century in one way or another. However, what really matters here is that this influence must benefit the Islamic world in particular and humanity in general. The first thing that comes to mind at this stage is whether the Islamic world can play such a role, given its present condition. No doubt, Muslims have the necessary ability and awareness to shoulder this responsibility. Since the era of the Prophet Muhammad (may Allah bless him and grant him peace), Muslims led the way in science, reason, thought, art, culture, and civilization, and produced many benefits for humanity. Muslims taught the world science, reasoning, medicine, art, hygiene, and countless other subjects. In order to restart the rise of Islam, powered by the Qur'an's light and wisdom, present-day Muslims have to acquire guidance based on the Qur’an’s morality and the Prophet’s (may Allah bless him and grant him peace) example. The Islamic world's disunity and fragmentation is an even more urgent and vital problem that must be resolved. The fact that the Muslims have not been able to form a powerful and active Turkish Islamic Union is a major contributor to many of today's ills. When a strong union is formed, such problems will either not arise or will be resolved far quicker than anticipated.
