What is the natural instinct
The natural instinct is the secret that lies in the soul. It is the essence of human creation, the secret of human existence. It is the reference of secrets in the existential sense of the truth of man. Its perfection completes the concept of man, otherwise this very meaning will be diminished and man will lead a life similar to that of the beasts.
Any damage that may happen to it will inevitably lead to a disturbance – according to its danger - in the existential meaning of man, and to psychological and social confusion, which overshadows the spiritual and physical existence of the meanings of life! Since the wounds of the instinct has degrees , just as the wounds of the body, scratching the skin is not like cutting the flesh, or breaking the bones, or stabbing the chest! As far as the nature changes, the corruption on the land spreads! It is one of the characteristics of the divine manufacture, and the divine creation of the humankind.
Therefore, the natural instinct is the first psychological image on which Allah created man, including the basis of balance and perfection. That is, before the intervention of the human hand with scratching.
Hence, human intervention in to change the natural instinct is completely a lost adventure, because it interferes with what is not known to him; the creation and the essence of his existence! Therefore, he was forbidden to extend his reckless hand to its box trying to tamper with its secret! The corruption of any meaning from its truth can not be avoided by the reform an ignorant, or any rectification of a dull! There is a need for the great Creator, who will not fall short to return it as he created it from the beginning!
Say, "He will give them life who produced them the first time; and He is, of all creation, Knowing.
Quran (36: 79
He alone - the Almighty - knows its secrets, and well acquainted with its composition. ( Does He who created not know, while He is the Subtle, the Acquainted?)(67: 14)
This is the requirement of the Prophet's profound statement (peace and blessings of Allah be upon him): " Every child is born with a true faith of Islam (i.e. to worship none but Allah Alone) but his parents convert him to Judaism, Christianity or Magainism, as an animal delivers a perfect baby animal. Do you find it mutilated?" in another narration in the Sahih of Imam Muslim: Allah's Messenger (may the peace and blessings be upon him) said, "No child is born but has the Islamic Faith, but its parents turn it into a Jew or a Christian. It is as you help the animals give birth. Do you find among their offspring a mutilated one before you mutilate them yourself?"
Reflect upon this fact, How impressive is this deep prophetic speech So interference in this precise meaning is but misguidance and following the self inclination. Therefore Allah made the religion the basis for the maintenance of this wondrous mystery in the meaning of human existence.
