Authored by Arab thinker Prof. Dr. Mohamed Osman Elkhosht, this encyclopedia offers an unprecedented, comprehensive treatment of both major and minor religions, sects, denominations, heresies, and spiritual and mythological currents. It goes beyond the mere presentation of beliefs and rituals to explore religions in their interactions with history, philosophy, theology, and modern intellectual developments— thus surpassing traditional encyclopedic frameworks. The encyclopedia emphasizes the importance of recognizing the “common grounds” shared among religions and philosophies, while also respecting the “qualitative differences” that distinguish them. It does not seek to erase doctrinal distinctions, but rather rebuilds the bridges between difference and coexistence, portraying religious diversity as a reflection of cosmic diversity. Key features of the encyclopedia include:

1. Comprehensiveness

2. Objectivity

3. Philosophical and metaphysical depth

4. Analyzing religion through human and social sciences

5. Establishing a renewed religious discourse

6. Balancing commonalities and distinction
