The Wisdom Behind the Prohibition of Pork

Question :

What is the wisdom behind the prohibition of eating pork?

Answer:

Allah's Knowledge encompasses all things. His Mercy, Wisdom and Justice extend over everything. So He, Most Glorified, knows what is best for His creatures, He is Merciful to them, and He is Most Wise in His Creation, His Disposal (of their affairs) and His Legislation and He has commanded them to do what will make them happy in the life of this world and in the Hereafter. He permits At-Tayyibat (all things good and pure) which benefit them and He has forbidden Al-Khaba'ith (all evil and impure things) which harm them. And Allah has forbidden eating the swine and informed us that it is unclean; Allah, Most High says:

"Say (O Muhammad): "I find not in that which has been revealed to me anything forbidden to be eaten by one who wishes to eat it, unless it be Maitah (a dead animal) or blood poured forth (by slaughtering or the like), or the flesh of swine (pork); for that surely, is impure or impious (unlawful) meat (of an animal) which is slaughtered as a sacrifice for others than Allah (or has been slaughtered for idols, or on which Allah's Name has not been mentioned while slaughtering).

So it is one of the Khaba'ith and Allah, Most High has said:
"and prohibits them as unlawful Al-Khaba'ith (i.e. all evil and unlawful as regards things, deeds, beliefs, persons and foods)."

It is well known that its food consists of rubbish and unclean. things, and that this is the most agreeable food to it-it pursues it and seeks it out. The experts have said that eating it (i.e., pork) causes worms in the stomach and intestines and that it decreases jealousy and self-respect, and eliminates modesty and chastity, and it has other harmful effects, such as indigestion. It also prevents some of the organs from secreting enzymes which aid in digestion of food. If what they say is correct, then these things are some of the harms and evils that it was forbidden for. And if what they say is not correct, then it is incumbent upon the rational person to trust in Allah's Information and His Judgement, that it is unclean, and to believe in the prohibition of eating it, and to surrender the decision about that to Allah. For it is He, Most Glorified Who created it, so He knows best about what He has put in it:
"Should not He Who has created know? And He is the Most Kind and Courteous (to His slaves), All-Aware (of every- thing).

And may peace and blessings be upon our Prophet, Muhammad and upon his family and Companions.
