Dear Veila Mast, you cannot prove a negative rather you need to prove the positive claim you are making ie Jesus is alive and in heavens. Islam is very straight forward that people live on this earth and no where else. They are born here, will die here and will be raised from here. A lot of nonsense has been attributed to the quran which opposes quranic concept of reality, which it uses to prove its arguments. If we just attribute anything to the quran senselessly it muddles up what the quran is trying to express.
Get out of interpreting the quran with invented reports in the name of ahadith. The way the reports make the big issue of 2nd comming of jesus the quran ought to say a lot about it but it does not. It just talks about jesus as a nor human. Why Allah tells us that my prophets are human from among you and proves the point by telling us they eat food like we all humans do. They walk in streets and have families etc etc.
This issue of 2nd comming of jesus is belief of christians which they borrowed from pagans of persia and egypt etc. Most of things attrinuted to islam as mazhab are actually perian inventions which they brought into islam when muslim conquered persia. It was a grand conspiracy against islam by them to take revenge. People need to read history about various things to see what has been happening.
The quran tells us that people do not live without air for breathing, water for drinking and food for eating. This is the way Allah has made us and set this world to work, so we should not go around thinking Allah has power so he can do this and that and the other. He had a purpose in mind when he decided to create the world and people in it. He has explain that purpose in the quran ie to put people through struggle for survival. So anyone who does best as per his advice will fair better and the rest who ignore his advice will suffer as per their own choice.
We have problem that we do not try to look at the whole picture of thing and start fooling around with bits which them contradict each other making the whole thing unnecessary chaotic.
If our molvies were that educated and thoughtful they would have figured out things but they did not instead many mislead us down mazhabi road. Islam is not a mazhab and deen is not about make beliefs aqeedah to fight over.
It is silly for any muslim to ignore the whole lot of verses telling us to be logical and rational and run after silly ideas and try to bend the quranic verses just to try and justify our make beliefs. We couldn't do worse in that case and we should all be able to see the results so far. Ummah is in terrible mess in almost everything.
I think we should get away from mullaiyat and study things for ourselves and see how quran makes better sense in light of realities of life. It is because the quran is for living in this life the best possible way. That means that if we are not living that way then we are not understanding the quran the way we should.
regards and all the best.
