So? So you were incorrect. The Gospels reaffirmed the biblical law from old testament
No, they didn't.
upon which Sharia is also based.
It is certainly not based on OT law. Influenced by, but not based on.
So some Christians rightfully choose to ignore some or all biblical laws but the laws themselves don't change. And Muslims can and do ignore their religious laws when those laws become bothersome enough.
The difference is that Christian denominations which don't follow biblical laws believe that they genuinely don't apply in a theological sense, while Muslims who don't follow Shariah just call themselves secular or modern Muslims. Islamic and Jewish law are both vastly more extensive than any laws found in the OT alone.
It's as inherently arbitrary in Islam as it is in Christianity.
The focus in Christianity is on Jesus, while the focus in Islam and Judaism is on the law itself. That is what 'saves' them.
