This book narrates in detail the trajectory of the prophet Muhammad and the extraordinary events that led to the emergence of Islam in 7th-century Arabia. Exploring historical sources, the author reconstructs the childhood and youth of Muhammad, his marriage to the wealthy merchant Khadija, his spiritual quest, and the transcendent revelations he received, giving birth to the Quran. The book recounts the immense challenges faced by Muhammad in spreading the new faith amid the resistance of the leaders of Mecca, the migrations to Abyssinia and Medina, the first battles fought by the early Muslims, and the diplomatic and military conquests of the prophet who, with remarkable political skill, unified and consolidated Islam in Arabia. The work also delves into the early compilation of the Quran, the dilemmas of the early caliphs after Muhammad's death, and the gradual acceptance of Islam among the Bedouin tribes. A meticulous and eloquent account of the extraordinary events and influential figures that shaped the birth of Islam and its historical course.
