An animal can be blindfolded and transported hundreds of kilometers away from its home, but astonishingly it is able to make its way back. Scientists have undertaken different experiments to understand how birds find their direction, but they have never been able to neutralize this capacity either in a bird or in any other animal. Numerous waves are broadcast from every corner of the globe, waves which may be received elsewhere, yet we are totally unaware of them. There is no scientific proof negating the possibility of revelation. The fact that science has been unable, down to the present, to discern the sources of revelation does not mean that the fact of revelation should be regarded as a scientifically unacceptable phenomenon.
Revelation is a particular mode of awareness and perception that occurs in certain rare individuals.
The nature of that awareness is clear enough to them, and if it is unknowable to others, it is because they do not find in themselves that mysterious superawareness. However, through studying the properties and effects of that form of awareness, they can discern the truth or falsehood of those who lay claim to it and see whether or not they truly possess that great and abundant source of knowledge. The word revelation is used frequently in the Noble Quran, and its various occurrences demonstrate that revelation is not confined to human beings. However, the unfolding of revelation is connected to the general progress of all beings toward perfection, and the highest stage of revelation, which the human being alone is fitted to receive from the world of the unseen, consists of that which God sends to His chosen Messengers based on the need of them for Divine guidance. The laws and the order which govern the whole expanse of being and on the basis of which all things take shape, demonstrate that the whole of being is imprinted with a certain revealed law.
