Book excerpt: The main premise on which this book rests is that the belief that all prophets including Jesus and all divine revelations including the Injil had basically the same beliefs – Islam. Thus, this work examines whether the Gospel of Barnabas actually promotes Islamic beliefs about Jesus and the Injil. The method used is that of comparing the beliefs of Islam using the Qur’an and Hadith to that stated in the gospel. The major area which this book examines is the isnad of the gospel to establish whether it is authentic according to Islam. This work covers new ground as it critically explores the Islamic credentials of the gospel.
