Wahi – Divine Inspirations and Revelations
Study of Parapsychology
As discussed earlier in the Mystery of Soul that modern psychology calls psyche what religion calls a soul. The psychologists remain busy studying and investigating psyche - the conscious living power within human body - and its various abilities. Studying the psychic phenomena in human bodies has led the psychologists to also study parapsychology subject. The parapsychology subject in particular deals with human behavior beyond the five physical perceptions (sense of taste, touch, smell, sound, sight) i.e. extra sensory perceptions also called sixth sense. This subject has resulted in the formation of various modern search organizations such as the Society of Physical Research in UK, that has been working and experimenting on telepathic communication, since their inception in 19th century. Then there are several OBE research & training facilities studying and attempting to practice the phenomena of Out of Body Experience, which is widely discussed these days especially in the context of near death experiences related by certain people, during unconscious state in an accident or a major surgical procedure, where they noticed themselves somehow they were out of their own body. Even though the experiments conducted by these research groups do not carry strong evidence yet their results do prove psychic abilities within humans.
ESP (Extra Sensory Perception) Among Certain Animals & Birds
The extra sense perception faculties among animals and bird is well known and confirmed even through modern scientific research. According to Helmut Tributsch of the Free University of Berlin, human skin is quite damp, due to secretions of sweat glands. On the other hand animals have relatively dry skin. As opposed to human skin an animal’s fur gets electrified with static charge when electromagnetic disturbances precede an earthquake and large amounts of static electricity build up in the air. This extra sense perceptions allows them to react such as horses break free, dogs bark violently, and cats move their kittens out of doors. Similarly birds can view the ultra violet rays of light due to special receptors they carry which are not visible to human eyes. These findings of extra sense perception behavior in birds have confirmation in ahadith of Prophet Muhammad ﷺ who said that ‘Angels are created of Nur (light)’ and ‘Shayateen (jinn devils) are created of a smokeless fire’ and their presence is felt by certain birds & animals: “when you hear the crowing of the roosters, then ask Allah of His bounty, for verily they have seen an angel. When you hear the braying of a donkey, then seek refuge in Allah from Shaitan, [the rejected] for, verily, it has seen a Shaitan.” A donkey's ability to detect jinn radiation or energy is similar to the ability of a snake to detect infrared radiation emitting from their prey whom they can strike even in the absence of physical light. It is a fact that certain snakes have holes on their faces called pit organs, that can detect infrared radiation from warm bodies from a distance. This unique extra sense ability allows them to see an image of their predator even at night, as an infrared camera does.
The Prophets Extra Sensory Perceptions
Keeping the ESP theory in mind it seems as though the Prophet ﷺ, due to his spiritual status, had paranormal forms of sense perceptions activated that provided ability for him to connect with the unseen world (of angelic existence) through, may be, some sort of an electromagnetic frequency. The electromagnetic spectrum  on our planet and in outer space have undiscovered frequencies which may carry the possibility of connection with one of our hidden senses to give us more knowledge in to the happenings of Al-Ghayb (Unseen) - an essential part of Islamic faith. This made him available for receiving divine inspiration and revelation (Quran) as explained in his own wording: "Sometimes it is (revealed) like the ringing of a bell, this form of Inspiration is the hardest of all and then this state passes off after I have grasped what is inspired...”  or as one of most knowledgeable companions Abdullah ibn Abbas (r.a) said "Allah's Messenger (ﷺ) stayed in Mecca for fifteen years (after his advent as a Prophet) and he heard the voice of Gabriel and saw his radiance for seven years but did not see any visible form, and then received revelation for ten years." Scientific research also confirms that there is radiation generated from the scalps of our head due to an intense neural activity taking place inside the brain and Electroencephalography (EEG) is an instrument used in monitoring such brain waves. Theta waves detected at 3 to 8 hertz frequency are patterns of neural activity monitored during deep sleep and meditative state. These waves are one of major indicators of brain activity related to learning and intuition. These are activated when we are disconnected from our normal consciousness and senses with the external world. The ability of Prophet to access divine communication through extra sensory perception ability can be compared to Prophet Suleiman (alaihi salaam) (Solomon) ability to hear communication between ants as mentioned in the Quran: "till, when they came upon a valley [full] of ants, an ant exclaimed: "O you ants! Get into your dwellings, lest Solomon and his hosts crush you without [even] being aware [of you]!" Thereupon [Solomon] smiled joyously at her words..." As Prophet Suleiman (a.s) along with his army approached an ant dwelling, he heard them communicate warning to each other. Today its a scientific fact that many insects including ants communicate with each other using pheromones, sounds, and touch. In fact they excrete different types of pheromones for different reactions such as alarm pheromones for danger. Therefore we should no longer be surprised when reading that a prophet of Allah heard them communicate. But what amazes us and baffles science is how did he manage to hear them and through what phenomena? This can only be answered if science dwells deeper in to the study of parapsychology and take religious view in to consideration especially knowledge and experience shared in Islam.
