The Holy Quran-the last...
(30:30) The logic of the Quran is unique and no scholar or scientist till now has been capable of such logic, no matter how much we study them. We challenge all those claiming to have found a better logic, to prove the contrary. Indeed, is there any logic as good and decisive? This question will be clearly answered once it is explained why human nature should be the basis of all laws and regulations.
It is a commonly accepted fact, both by past and present philosophers, that every living being is endowed with a mechanism through which its survival becomes possible. Experimentation and the subsequent results have proved this beyond all doubt. Obviously there is little need for proofs or advanced technical reasoning and a brief study of the life of living beings, plants or animals will easily point to this fact.
For instance, it is common knowledge that a living being needs food for its survival. However, every living being or species needs different kinds of food according to its bodily needs. Moreover, nature has equipped each living being with a certain digestive mechanism which speaks for itself, for the purpose it has been created and the food that suits it.
A study of the digestive system of the herbivorous and carnivorous animals and the existing differences between their teeth, stomachs, bowels and so on, can be a true testimony and a decisive evidence to prove our point. Hence, a scientist, instructing how animals should be fed, must take into account the difference in the digestive mechanism of these animals and upon which, he should subsequently base his instructions.
Of course, since animals act through instinct, and not reason, they do not need to be instructed as far as their nourishment goes, though animal husbandmen may need instruction in feeding and breeding the animals.
