""Like the exhibition the book accompanies, Hijrah: In the Footsteps of the Prophet sets out to rectify a 1400-year-old lacuna in our knowledge of a world-changing event, of which details have remained tantalizingly out of reach. Kaleidoscopic, learned and exquisitely illustrated, the book represents a major step in rectifying this imbalance while shedding new light on an event that continues to be of inspiration and relevance, regardless of one's background or faith.""-- ""The National"" ""Hijrah: In the Footsteps of the Prophet is built on the exhaustive research and fieldwork of Abdullah Hussein Alkadi, one of the world's leading authorities on the Hijrah. Alkadi has spent decades studying and travelling the exact route the prophet and his companions took across the desert, as well as exploring the wider story, life and legacy of this journey.""-- ""The Art Newspaper""
