The Koran denied the crucifixion of Jesus
They did not kill him nor did they crucify him though it was made to appear like that to them. They certainly did not kill him. God raised him up to himself.”
Well, that's what the Qur’an says, but even the most liberal and sceptical of biblical scholars today will affirm the historicity of the resurrection. Let me give you just one example. This comes from Bart Ehrman, a New Testament scholar who's very critical of the Bible—no friend of Christianity—but he says this in one of his works: “one of the most certain facts of history is that Jesus was crucified on orders of the Roman prefect of Judea Pontius Pilate.”
So the challenge for Muslims is this: why should we believe one verse in a book written in Arabia six hundred years after the life of Jesus rather than multiple sources in the New Testament written within decades of the events and based on eyewitness testimony?
