Every human being has some experience about supernatural phenomena. Incidents are ironclad that are hard to explain. Many people have such experiences in their personal lives, while there are many who can learn by listening to other people's experiences. And creates a similar image in the imagination itself.
In my opinion, supernatural phenomena are difficult to analyze scientifically, but can be explained from a religious point of view.
I would like to share an incident with you. The phenomenon is a little different. You may not be too scared to know this, but I believe it will sow the seeds of fear in your mind.
The incident was observed many years ago by the imam of a mosque in Rajbari district of Bangladesh. A Imam of the mosque (Imam like father of the church) was standing in the Mosque after Esha prayers. Other worshipers left the mosque after the prayers. He was alone in the mosque. After some time, two persons called Imam from outside the mosque. When Imam came out of the mosque, they requested Imam Sahib to bury a dead person. Imam used to do this kind of work from time to time, so he easily agreed. He started walking with the two men to the dead man's house. The house was in the village. There was a quiet silence all around. Imam was a little surprised when they arrived at the house of the deceased. There were no people in or around Karan's house. Usually when a person dies in a rural area, there are many gatherings. But there were no people in that house. Then he became frightened and asked them why there were no people in the house. They did not answer. They told Imam that the dead person has been kept in the room so you come in the room. Imam entered the room and saw the dead man lying in the room and covered with a cloth. And there are a few more people standing around the dead man. They asked Imam to start burial of the deceased, such as bathing, janaza and burial. Imam started removing the cloth from the dead person, then he saw the face of the dead person and shouted Allahu Akbar. Because the face of the dead person was not like that of a human being, it was like that of an inferior creature. He tried to leave the room in fear, but was stopped by other people. They asked Imam not to go. They said the dead man was a black magician. Such a change has taken place in his face after death. The rest of his family has been relocated so as not to be intimidated by the situation.
Black magic is a form of witchcraft that harms other people. Those who practice black magic are cursed and sinful. Devil is appeased by black magic. They worship the devil. Allah does not like them, who are do this. Many of them are being punished for their sins in this world.
I heard this incident from a man. He was a close of that Imam. He assured me of the truth of this incident.
