c)selection of food
The prohibition of the eating of pork in islam is a forward step in materialistic education . This leads automatically to deeper understanding of the need for the culture of a pure human nature. As blood is virturally our life and what we consume ultimately affects the blood system . it is therefore necessary to excercise choice in the section of our food and drink. It is quite obvious that the more man has advanced in civilisation, the more carefully he selcts his food. we also know that the uncivilised people of the world in the past were canibals. they start to select food when they reach the door of a higher cutlure. they also lose their preivious inferiority complex. these are the proofs supporting my statement.
the advance of human nature into its purest from does not end in the abstinance from pork eating. the eating of flesh of creatures which die a natural death or in the course of fighting be they cattle goats or poultry is equally forbidden by islam. we do not know if scientists have made a study of flesh or blood of animals which have died as a result of fighting but we muslims are tuaght not to consume the flesh of those animals.
apart from the above and as a matter of principle, muslims do not eat the flesh of animals of prey such as the lion, gtiger, leopard, snakes and even cats, dogs rats, etc. this prohibition is based on the purification of ones nature. because food when consumed does not merely enter the intestines and becomes excreta . it is absorbed in to the blood system and circulated to all parts of the huamsn body including the brain and this in no small way affects mans nature.
islam allows muslims to p arake of clean flesh, it neither prevents nor enocourage anyone to become vegetarians. however in the consumption of flesh, muslims are require to be selective. some people have argued that the modern pig is given only clean food and therefore its flesh should be consumable. the answer to this argument is this. you the feed the pig with clean wholesome mash but you cannot change its nature. it is still a pig. a pig is not a plant and you cannot change it by bud grafting.
