Over the last thirty years, humanity has discovered thousands of planets outside of our solar system. The discovery of extraterrestrial life could be imminent. This book explains how such a discovery might impact Islamic theology. It is the foundational reference on the subject, comprising a variety of different insights from both Sunni and Shi'i positions, from different Muslim contexts, and with chapters that compare and contrast Islamic perspectives with Christianity.
