This book stands out, offering a unique discussion unlike any other in its genre. It delves into the historical facts detailing the rise and diffusion of Islam during and after its remarkable era of civilization, based on the theory of 'The Impact of Revelation.' The essence of revelation inspired Prophet Muhammad (s.a.w) and his followers to propagate the teachings of Islam across the Arabian peninsula. Subsequently, the faith continued to flourish, transitioning from the Caliphate of al-Rashidun to the Umayyad Caliphate's rule until 750 C.E. The Abbasid Dynasty then ascended to power, overthrowing the Umayyad in 750 C.E. During Islam's Golden Age and beyond, Muslims were motivated to extend its reach beyond the Arabian peninsula, encompassing Turkish and Persian kingdoms, ultimately expanding into Central Asia. The profound impact of revelation in the rise and expansion of Islam is evident today, with the religion being the official faith in numerous countries across Asia, sub-Saharan Africa, North Africa, and the Middle East, experiencing unprecedented growth on a global scale.
