Not everybody is even
aware of Islam. [ apart from portrayals in the media ]
Not everybody has even
read the Qur'an.
Taking one Scriptural verse from the Bible or Qur'an in order to "prove" a point is a very weak argument.
Sound religious knowledge takes years to develop, and does not depend on a handful of cherry-picked verses.
I could do the same as you, and select a verse from here or there that appears to say what I want it to say.
You only have to look at different Christian denominations, arguing over verses in the Bible on RF to see how futile this .. some threads just go on and on.
[eg. Is Jesus God? etc. ]
There are numerous references to "the People of the book" in the Qur'an, and inter-marriage is acceptable in some circumstances .. much like Protestants and Catholics.
It is more about piety than creed..
I like attending different churches .. we are not all bigoted know-it-alls.
As far as I'm concerned, God is God !
..and we all have something to learn, regardless of creed.
..and finally, one more point.
Jews do not accentuate what happens to us after death.
They realise that they will be blessed in this life if they keep "the law".
..so I visualise the after-life as being similar to a continuation of this life,
the difference being that this worldly test will be over, and all our deeds will be laid bare.
