As an example...
As an example, we may say that a green-tipped shoot, emerging from a single grain in the earth, is "aware" of its future existence as a plant which will yield an ear of wheat. By means of its inherent characteristics, the shoot acquires various mineral elements for its growth from the soil and changes, day by day, in form and strength until it becomes a fully-matured grain-bearing plant - and so comes to the end of its natural cycle.
Similarly, if we investigate the life-cycle of the walnut tree, we observe that it too is "aware", from the very beginning, of its own specific purpose in life, namely, to grow into a big walnut tree. It reaches this goal by developing according to its own distinct inherent characteristics; it does not, for example, follow the path of the wheat-plant in fulfilling its goal just as the wheat-plant does not follow the life pattern of the walnut tree.
Since every created object which makes up the visible world is subject to this same general law, there is no reason to doubt that man, as a species of creation, is not. Indeed his physical capabilities are the best proof of this rule; like the rest of creation, they allow him to realize his purpose, and ultimate happiness, in life. Thus, we observe that man, in fact, guides himself to happiness and well-being merely by applying the fundamental laws inherent in his own nature.
This law is confirmed by God in the Qur'an, through His Prophet Moses, when he says, " Our Lord is He who gave everything its nature, then guided it " (20:50).
It is further explained as: " He who created and fashioned in balanced proportion and He who measures and guides " 87:2-3 As to the creation and the nature of man, the Qur'an says, By the soul and Him who fashioned it and then inspired it with wrong action and fear of God; he is truly successful who causes it to grow and purifies it and he is a failure who corrupts and destroys it . (91:7-1O).
God enjoins upon man the duty to " strive towards a sincere application of the din ," (that is, the fitrah of God, or the natural code of behaviour upon which He has created mankind ), since " there is no changing the laws of the creation of God " (30:30). He also says that " In truth, the only deen recognized by God is Islam " (3:19). Here, Islam means submission, the method of submission to these very laws.
The Qur'an further warns that " The actions of the man who chooses a din other than Islam will not be accepted " (3:85).
