Gospel of Barnabas
Standard Muslim teaching asserts that the "Injil" Arabic name for the Evangel or the prophetic Gospel delivered through the prophet "Isa" (Jesus of Nazareth), has been irretrievably corrupted and distorted in the course of Christian transmission. In consequence, Muslim teaching asserts that no reliance can be placed on any text in the Christian tradition (including the four canonical gospels of the Christian New Testament) as truly representing the teachings of Jesus. Viewed from an orthodox Islamic perspective, the Gospel of Barnabas might be considered a Christian work, as its many points of difference from the Qur'an suggest; hence, it too may be expected to have undergone corruption and distortion. Consequently, no orthodox Muslim writer accepts the Gospel of Barnabas as transmitting the authentic "Injil", and few deny that the known Italian text contains substantial elements of late fabrication. Additionally, the Gospel of Barnabas cannot even be a variant of the authentic "Injil" because the real "Injil" must be authored from the perspective of Allah the same way the Quran is supposed to be, and not from the perspective of Barnabas. Nevertheless, Muslim writers sometimes note those elements of the Gospel of Barnabas that stand in accord with standard Qur'anic teaching, such as the denial of Jesus as being Son of God and the prophetic prediction by Jesus of the coming Messenger of God and, consequently, some Muslims are inclined to regard these specific elements as representing the survival of suppressed early Jesus traditions much more compatible with Islam.
