Belief in the invisible realm of existence and the beings inhabiting it is another essential of Islamic faith. Since our sensory powers are limited, it is not wise to deny outright the existence of realms beyond our senses. Also, we know so little about existence that what we do know is considerably less than what we do not. Our sciences are still in their “childhood,” and the future will witness dazzling scientific discoveries and developments.

Sciences are supported by theories and develop through trial and error investigation of those theories. Numerous “established” facts were once considered false, and many other “established” facts are now known to be incorrect. We accept unquestionably, and without any scientific basis, the existence of many things. Since the beginning of time, most people have believed in the existence of the spirit and angels, jinn and Satan. So, it would seem to be more scientific to allow their existence in theory and then investigate it. Denying their existence is unscientific, insofar as such a judgment or conclusion must be based on concrete proof. No one can prove and therefore scientifically claim the non-existence of the invisible realm of existence.

Many physical qualities, such as heat and cold, and such abstract qualities as beauty and charm, and feelings of joy, sorrow, and love, can be experienced directly and measured to some degree. Materialists attribute these to some biochemical processes in the brain, and some scientists (like psychologists and psychiatrists) still try to explain them by natural or physical laws. However, our non-physical side (namely, our feelings, beliefs, potentialities, desires, and so on that vary enormously from individual to individual, although everyone has the same material elements) is too profound to be explained by physics, chemistry, or biology.
