Who is Allah? What does He ask of those who submit to His teachings? Pulitzer Prize-winner Jacke Miles gives us a deeply probing, revelatory portrait of the world's second largest, fastest-growing and perhaps most tragically misunderstood religion. In doing so, Miles illuminates what is unique about Allah, His teachings, and His resolutely merciful temperament, and he thereby reveals that which is false, distorted, or simply absent from the popular conception of the heart of Islam. So, too, does Miles uncover the spiritual and scriptural continuity of the Islamic tradition with those of Judaism and Christianity, and the deep affinities among the three by setting passages from the Hebrew Bible, the New Testament, and the Qur'an side by side. In the spirit of his two previous books, God and Christ, and with his characteristic sensitivity, perspicacity and prodigious command of the subject, Miles calls for us all to read another's scriptures with the same understanding and accommodating eye that we turn upon our own.
