This book explores tazkiya therapy, a holistic psychological approach based on Qur’anic guidance and rooted in the understanding of human beings as multidimensional –that is, physical, psychological, social and spiritual beings. The book starts with a detailed explanation or the object, the process and the purpose of tazkiya therapy, along with an account of the boundaries and the enabling factors of the approach. Rather than a singular theoretical framework, tazkiya therapy is a dynamic and flexible approach that integrates multiple frameworks and disciplines to grow the human soul, cognition, emotion and behaviour. Although it is a multidimensional approach, the process of therapy is step-by-step, and the middle part of the book presents the key stages in the approach. Within these steps, the therapist is given seven different approaches that they can customise to the needs of the client depending on whether they need assistance with thinking patterns, emotional disturbance, a behavioural problem or a dysfunctional nervous system. The book ends with a comprehensive summary of the model, a series of case studies, a future outlook on training and an application for continuing the study and practice of tazkiya therapy. This book, based on the foundation that tazkiya therapy covers issues that are spiritual in nature and always connects to Allah in facilitating the healing process, will fulfil the needs of practicing Muslim psychologists, psychiatrists and students of psychology and Islaic studies.
