A fresh perspective on medieval Islamic medicine through the history of time, ethics, health, and the human body.Time shapes every aspect of medicine. It governs birth and aging, illness and recovery, the changing seasons, and the rhythms of everyday life. In turn, medical time is shaped by the encounter between physician and patient. It also reflects the histories, cultures, politics, and environments in which people live. Ahmed Ragab's In Good Time reveals how medieval Islamic physicians understood time as a dynamic cultural, ethical, and intellectual force that informed both medical knowledge and the experience of health and disease.Drawing on a rich body of medical, religious, philosophical, and historical sources, Ragab examines how physicians understood time and its role in every stage of clinical practice. They considered the progression of disease, the timing of treatments, the changing body across the course of life, seasonal and environmental influences on health, and even astronomical and astrological observations. Medical practice unfolded alongside prayer, religious calendars, scholarly traditions, and social expectations, creating a clinical culture in which scientific inquiry, daily life, and spiritual practice were deeply interconnected.By placing temporality at the center of the history of medicine, In Good Time offers a new perspective on medieval Islamic intellectual life and challenges familiar assumptions about the relationship between medicine, religion, and culture. One of the few books to address the concepts of time and medicine together, this book demonstrates that understanding how medieval physicians cared for the body requires understanding how they understood time itself.
