There cannot be such a creation as Allah promises an eternal life in the here after.
Yeah it sounds not enough for the person who has not experienced any truth. But the reality is, the rest is an eternal life. Allah has offered us eternal Life.
And brother, as u said, its not only about going to heaven or hell, but the main part is about being with and seeing Allah!
Because even in heaven there would be people who got there by the intention of enjoying the paradise alone. They may not see Allah! only few see Allah. They are called Mu'mins.
And seeing Allah is the Best joy of All. Its not just a word. Seriously, it IS the BEST ENJOYMENT ANYBODY can ever get....meaning, the enjoyment is beyond our imagination! And iam not blundering (if u r hearing this for first time). :)
