Psychology is one of the most intriguing scientific disciplines as humans are inherently curious about their own nature. Ironically, there are a multitude of theories and explanations that mislead and confuse the very same creatures that they are meant to describe. Allah has blessed us with guidance in all facets of our lives, including that of our own souls and psyches. Islam offers an uncomplicated, comprehensive, and precise theory of our spiritual nature, our purpose and priorities in life, and how we can attain serenity and happiness in this life and the next. This book is a humble effort to expound upon the true conceptualization of human psychology based upon the Qur’an and Sunnah. Moreover, Dr. Utz includes specific references to scientific research that corresponds to, and builds upon, what is already known from revelation.
