Text in Arabic. This book aims to shed light on one of the most prominent figures in human history: the Chinese sailor and Muslim admiral Zheng-He (in Arabic, Hajji Mahmoud Shams). The book examines his geographical discoveries and his seafaring travels. Zheng-he visited all of the countries located on the coasts of the Indian Ocean, South Asia, and African East coast during the first third of the fifth century (Hijri calendar), between 1405 – 1433). His voyages were known as Rahlat Al-Kanz, or Voyages of Treasure, and were a compilation of seven different marine expeditions over the course of 28 years. An important issue explored in this book is that of Zheng-He’s arrival to the American territories, a discovery that he made before Christopher Columbus. Specialists in history, geography, and archaeology provide their opinion and research regarding this claim.
