This book provides a brief overview of the life of the leader Salah Al-Din Al-Ayyubi. I wanted to present the West's vision of the qualities, characteristics, and defects of this legendary Muslim figure by translating various English and French sources, as well as consulting Arab sources regarding some historical and religious details, thus multiplying the angles of reading his history. I was impressed by their presentation of the truth without exaggeration, along with their constructive evaluation and criticism. If this is the opinion of the West (the Crusaders) about him, then what about the truth of his personality from the point of view of his contemporaries? There are areas that are not highlighted in his biography; we know a lot about his achievements, but we know very little about his personality, just like many other rulers of the Middle Ages. The last three chapters of the book deal with what we can learn from this character, and how we can benefit from his morals and actions. I hope that you will enjoy and benefit from this work.
