As all things that man eats and drinks have their cold and warm effect on man's body, and to a certain extent on man's mind, so, especially with animal food, it is natural that man should partake of the quality of the animal he eats. The pig was particularly pointed out, both by Judaism and Islam, as the forbidden animal. Besides many other reasons, the chief reason was that if one can observe, comparing the life of the pig with that of other animals, it will prove to be the most material, regardless of what it eats, blind in passion, and without the faculty of love and affection. The dog also, and the cat, and all carnivorous animals, were considered, from the hygienic point of view, Haram, unwholesome, and the people who have made use of their flesh as food have realized that its effect upon their bodies and minds is harmful.
