I am of the same view as is expressed in the above article. I do not believe that vehicles or water or other liquids moves upward by the force of Jinns. It moves because of gravitational force of "gravity hills".
There is a complete chapter in Holy Quran about Jinns. There is Masjid Jinn in Makkah where Prophet Mohammad (peace be upon him) is believed to have accepted baiyat of Jinnat. As a Muslim I do believe in all what our religion says about Jinnat. But science does not accept this theory. I do not believe in stories related to jinns by so-called Aamil Hazrat and Pir Sahiban. I totally reject the idea of Jinn overcoming/loving a human being, especially beautiful girls. It is all masterly crafted drama. I also do not subscribe that there are Jinnat in Baiza Valley. I believe in Jinns but not the Jinns of Madina Valley of Jinns. It is just an interesting phenomenon.
