Emad:
something extra to God?? oh Lord…that is indeed the fruit of a wordly mind.
In fairness, I think part of the problem here is that Christians and Muslims (and Jews) have a very different concept of the body vs. soul.
Christians seem to see a clear distinction between the two, and the things that are good for the soul are what you’ll find in heaven.
I know for certain that this split is not characteristic of Judaism, so perhaps Emad can tell us about the body and soul in Islam. I can imagine perfectly well that a formless, shapeless heaven would make no sense to a faith that does not recognize a hard separation between bodily and spiritual things.
