Jesus in me
You have misquoted it.
It does not say all of those things you have said above brother.
"Woe to those who write the book with their hands and say this is from God" means some will write on their own and claim that is of divine origin. It does not mean all those added, corrupted, ignored some curse of Moses etc etc. Its just simple language.
On what basis do you say this is speaking "only" about corruption of previous scripture, and it refers to Jews or Christians alone etc? You are wrong. This is addressing all. Even those who call themselves Muslim. Anyone.
I believe it was all unsupported noise. They don't want to know the truth because then they can see how far short they fall.
Of course I believe the Hadiths qualify as man written dribble. The texts themselves reveal it.
