[Ali Imran]

I am asking you in all fairness to show me the Injil..how do you know that the Injil is not a compilation of the 4 gospel writers .. have you seen the Ịnjil? Muhammad has seen it, Allah says it is with us

pls show me proof from the Quran

It is widely believed that accounts of Jesus' life and teachings, which eventually became the Gospels of Matthew, Mark, Luke, and John, were initially transmitted orally. This oral tradition served as the source material for the written gospels.

No, I cannot show you the Injeel that came out of the mouth of Jesus. I believe it was never recorded. There is no evidence of it ever being recorded.

When you read Mark or any of the 4 Gospels, you see words that came from the authors. Do you think those words are the Injeel in our paradigm? If you think that, you're mistaken. 

Do you know that many other similar Gospels were also written, but they weren't selected by the unknown Bishops to be included in the Bible? There are manuscripts of the Gospel of Thomas, the Gospel of Peter, the Gospel of Mary, and others.
