Yes, I've actually thought about this before. When I was "losing my religion" at the tender age of 14.
The fear of hell stuck to me. It was like the fear a kid has after watching a scary movie. I was terrified...because I loved rock and roll...and the preacher on TV said it was evil, but I loved it so much. Finally it drove me into a crazy depression, and my father told me there was no such thing as hell.
It happened again, years later when studying the quran. I would read it, and it had the most graphic descriptions. Ghastly stuff. It really pushes the fear button. I, a grown man, would lay in bed with this odd fear. The same kind of fear as right after seeing a really freaky horror movie. You know what I mean. Where you know there are no zombies or boogymen, but you leave the hallway light on anyway (not me of course..I aint scared of notin

)
Like going to beach after watching Jaws. You know that giant great white sharks are not coming to hunt you down, that shark attacks are very rare, that great whites dont even attack people on purpose....that great whites dont even swim in these waters.....you know all that....but just after watching that scary shark movie, you have a fear of going in the water.
I have a friend who is a marine biologist, and she will not let her kids watch Jaws, because she does not want them to get an irrational fear of the ocean.
What happens to those who died without having been in contact with Islam or Muslims? It would seem illogical for them to have to endure hell, which must mean that some non-muslims who lead righteous lives do not go to Hell.
Indeed. Therefore isn't giving Dawah in itself a bad thing, since giving Dawah will cause more people to have contact with Islam, with the result that some people still do not accept Islam, and therefore end up in Hell.
If there had been no Dawah, then everybody would have been ignorant, and nobody would have gone to Hell.
Realistically, you are correct.
From a christian viewpoint, it would have been better if Jesus dies for everyones sins.....Then just kept it on the down low. Hooray, everyone saved, right?
By telling people the story, knowing that some or many would not believe you, you would basically be causing their damnation. Not only that...but the whole mission of "saving everyone" fails.......How perverse and illogical is that?
From a muslim viewpoint, from what I know, it would not matter.
Allah decided who was going to hell already, if you believe in him, it is his will...if not.....it is his will. So, I really dont get how that works out.
I guess the answer would be, it would not matter, since if you gave dawa to a "person of the fire" they would reject it anyway because it is their nature (because allah already damned them before they were born, so they are just fulfilling their destiny) and if you gave dawa to a person who allah had created to go to heaven they would accept it no matter what.
So it is not really in the hands of the dawa giver.
Correct me if I'm wrong
