Although much simpler than the dietary laws followed by the Jews and the early Christians, the code which Muslims observe forbids the consumption of any part of the pig (flesh, fat, etc...), and any kind of intoxicant - whether it be solid such as drugs, or liquid such wine and beer.
The Prophet of Islam said “Your body has rights over you”, and the consumption of wholesome food and the leading of a healthy lifestyle are seen as religious obligations.
Muslims are only permitted to eat meat that is termed ‘halal’ which means that it has been slaughtered according to the Islamic law.
Regarding food, Allah instructs the following to the Prophet:
“Say: I do not find in that which has been revealed to me anything forbidden for an eater to eat, except that it be what has died of its’ self, or blood poured forth, or the flesh of swine - for that surely is unclean...” (al-Qur’an, Chapter 6, Verse 145)
With the exception of intoxicants, swine, some wild animals, products from animals not slaughtered in the Islamic manner, certain marine animals such as crab and lobster and fish that without scales, most other foods are permitted in Islam.
