The value system which finally governs man's conduct could be laid down by man himself or it could have a super-human force. The best system of faith and value pattern for human beings must be the one which has a close proximity with the nature of man. This is the only rightful system which could be suitable and beneficial for him. Certainly man has not created himself. He is one of the creatures of a supreme Being, namely, Allah.
Man is the best of all creatures and has been created in the most suitable proportions.
Since man has not created himself, he can have no claim whatsoever to possess an ultimate knowledge of himself and his nature. Consequently, if he tries to create a value system for himself, he is not able to evolve it in accordance with his own nature. Even if we presume that he might evolve a value pattern which may be close to his own nature, he cannot claim a certainty on this score, as he, being the subject of his own nature, cannot claim to have a total understanding of it. It is only the Creator, Allah, who has total knowledge of man and his nature. Since man's created value system cannot, with confidence, be claimed to be totally in accordance with his own nature, it cannot be the perfect system which could be followed completely without giving rise to situations of conflict between that man-made value system and human nature.
