Muslims believe in the world which is not seen by anyone which include angels, heaven, hell, Satan and jinn. i am Astro Spell (Muslim Astrologer). people always ask me about the existence of Jinns. The reason behind this believe are many verses of Quran. According to that angels were created from light and jinn from Fire. Even in other religions there are bad spirits, satan, witchcraft. The most important thing is we can read about them in Quran. So, we can not question about its existence. Moreover we came to know about many stories about jinns. That i will tel you about in my other blogs. In One of my other blogs i have also explained how to call jinn.
