Is the Injil (gospel) mentioned in the Quran, the New Testament?
It is not the Injil that was given to Jesus. The first attempt to write the Injil was some 50 to 70 years after Jesus. In fact the first traces of writing was that of the Book of Thessalonians in the New Testament written in the year 50 52 AD. The Book of Romans was written 57 years after Jesus. The Book of Revelations was written 95 years after Jesus. So the original Injil given to Jesus was not written in the life time of Jesus and hence the present New Testament cannot be said to be the Injil. In addition Jesus spoke Aramaic, a Hebrew dialect, this original Aramaic Injil is non-existent.
