In this book, the administrative system is explored in the Prophet Mohammad’s (PBUH) system and traditions which date back to about 1400 years ago. This investigation included not only Prophet Muhammad’s (PBUH) speech, which was considered as his general policies and the policies of his mission, but also his practical and behavioral traditions to indicate a model he practically used for reaching his goals. To make this study more comprehensive, the successful and traditional administrative systems in the modern world are also mentioned and the two systems are analyzed comparatively. This book aims to lead the reader to an appropriate choice by reaching a proper understanding of administrative systems based on the comparison of Prophet Mohammad’s (PBUH) traditions with the administrative systems inspired from Western scholars’ minds and experiences.
