> I have heard Muslims believe that Allah will not inflict suffering on someone beyond what they can handle.

I find this a particularly inhumane way of thinking. Try saying that to someone suffering "oh, you can handle it", it's beyond cruel, yikes. Makes it sound like it's some type of blessing, like the little 3-yr old is meant to die of bone cancer because of some greater God's plan. I don't know, it's just sounds so wrong to me to think like that. Even life on earth is some sort of school for the afterlife, I don't think there is a lesson to be learned by dying of cancer as a young child.

> God, if they exists, could have created world we everyone were in a state of continually bliss, but what would be a point of that?

Yes please, isn't that what heaven is supposed to be?
