What do we know about Jerusalem, the first qibla of Muslims? Revered throughout history as “the city of the Friend of God” (Khalī- lullah), Jerusalem was a haven where people of all faiths lived in peace for most of its Islamic history, especially during the Ottoman period. Today, the Palestine issue remains a global focal point due to Jerusa- lem's sacred status, particularly as the home of the Al-Aqsa Mosque. This book aims to shed light on Jerusalem's history and importance. It answers 101 questions about the city's journey from its earliest days to the present, with a particular emphasis on its significance to the Abrahamic religions. This work serves as both a reference for those studying Jerusalem and a historical guide for those planning a visit.
