Malaikah (Angels) & Jinns (Invisible Beings)
A Modern Investigation & Analysis
Chris Line in his article Jinn from a Scientific Viewpoint suggests that jinns dwell in a parallel level to man, but due to their existing at a different vibratory rate, they are normally invisible to us. He suggests their belonging to the infrared part of our electromagnetic spectrum. Though no clear evidence of this theory exists yet it could be related in many ways to our knowledge of Jinns in Islam.
Electromagnetic radiation is a transmission of waves or particles at different wavelengths and frequencies within electromagnetic spectrum. Infrared radiation, like other radiations such as light or x rays, is part of this spectrum, a type of radiant energy invisible to human eyes but can be felt as heat. All objects in the universe emit some level of IR radiation, but two of the most obvious sources are Sun and Fire. Our earth absorbs radiation from the sunlight throughout the day and emits it at night. Chris suggests that if a being had a body of low-frequency Infra-red, it could live deep down inside the Earth, interpenetrating what we consider to be solid materiality. If correct, it explains the fact jinns dwelling inside the ground and their influence in the night as suggested in Quran: (Al Quran 113:03) ...from the mischief of created things and from the evil of night's darkness when it spreads. - The Prophet ﷺ said: "Gather your children when darkness spreads..., for the jinn are abroad and seize them.” The Quranic terms maarijin-min-naar (Al Quran 55:15) meaning "smokeless fire" and nar as-samum (Al Quran 15:27) meaning "fire of scorching winds" implies their fiery nature and invisibility because smoke releases from a burning of a physical object but their fire does not involve burning of any physical objects.
Chris also suggests they dwell and connect at a possible point where electromagnetic energy meets our psychic or extra-sensory perceptions. This implies their influencing our dreams at certain moments when our soul is connected with the spiritual world, such as the Prophet ﷺ said about a dream from satan: “... the evil dream which causes pain is from satan…” The suggestion of their belonging to an electromagnetic radiation may also explain the hadith pertaining to visual ability of certain animals to detect them: “..And when you hear the braying of donkeys, seek refuge with Allah from satan for (their braying indicates) that they have seen a satan.” According to Helmut Tributsch of the Free University of Berlin, human skin is quite damp, due to sweat gland secretion as compared to animals who have relatively dry skin. Electromagnetic disturbances precede an earthquake and large amounts of static electricity build up in the air electrifies animal’s fur with static charge. Often survivors have witnessed unusual behavior in the animals preceding an earthquake. Moreover 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. Vipers, pythons and boas have holes on their faces called pit organs, which contain a membrane that can detect infrared radiation from warm bodies up to one metre away. At night, the pit organs allow snakes to 'see' an image of their predator or prey — as an infrared camera does — giving them a unique extra sense.
