Islamic civilization has greatly influenced the West and Westerners, an influence denied only by the hateful and prejudiced. Many have tried to obscure this truth throughout various eras, but to no avail. The author here presents all aspects of Islamic civilization, having been exhausted by the criticism of the resentful and the falsehoods of Orientalists. He wrote this book in two separate parts: the first part is dedicated to refuting those who deny the influence of Islamic civilization on the peoples and nations of the West. The second part focuses on the various Islamic sciences and schools of thought, as well as governance and politics in Islam, reviewing the approach of the Prophet Muhammad in these matters, through the Rightly Guided Caliphs, up to the administrations of the Umayyads and Abbasids, then the Mamluks and Turks. The book as a whole serves as an excellent rebuttal to those who deny the impact of Arab and Muslim civilization and their renaissance on Europe.
