Each time I compare something religious to something else, religious people tell me you can't compare that. It seems religion is uncomparable.

I would be happy AFTER Allah removed my sins. I guess I can undestand that you look forward to the removal of your sins, but before that, you have to do your duty - fast.
Why isn't removal of sins a reward?

I can't see how it would prevent you from doing bad things, it that supposed to mean you are too hungry to rob a bank? Or you can't lure on people in the night, because you are busy eating?

I can see the point about getting a view how poor people feel, but I wouldn't look forward to that.
Maybe you have to be a muslim to understand...
