There is no way that Allah would ever and the Rock means ever send his only begotten Son to die for our sins.

There is no way that Allah would ever come down as a human and die for our sins. And I mean ever.

That is the whole contridiction. Did God come down and die. Now this is a big deal because if determines your view of God.

It determines your world view, it determines how one views salvation. It determines how one becomes righteous before God. Whether one is at peace with God or whether one is his enemy. etc

So the very foundations of both books are at total ends of the spectrum.
