Forbidden food substances include alcohol, pork, carrion, the meat of carnivores and animals that died due to illness, injury, stunning, poisoning, or slaughtering not in the name of God.
The main reason pork is forbidden for Muslims is because it says in the Holy Quran that some food is allowed, while others are explicitly declared haram, which means forbidden. And pork is one of those forbidden foods.
For a meat to be certified “halal,” it cannot be a forbidden cut (such as meat from hindquarters) or animal (such as pork). Beef, lamb, chicken, fish, venison, and game birds can all be halal. The only prohibited animals are pigs and reptiles.

In Abrahamic religions, eating pig flesh is clearly forbidden by Jewish (kashrut), Islamic (halal) and Adventist (kosher animals) dietary laws. Although Christianity is also an Abrahamic religion, most of its adherents do not follow these aspects of Mosaic law and are permitted to consume pork.
Islam teaches that pigs are unclean and eating pork is a sin, and some Muslims feel selling or handling pork is also forbidden because it would make them complicit in the sins of others.
Exposing the intimate parts of the body is unlawful in Islam as the Quran instructs the covering of male and female genitals, and for adult females the breasts. Exposing them is normally considered sinful. Exposing intimate parts when needed, such as going to the toilet or bathing, falls under a specific set of rules.
Dogs in Islam, as they are in Rabbinic Judaism, are conventionally thought of as ritually impure. This idea taps into a long tradition that considers even the mere sight of a dog during prayer to have the power to nullify a pious Muslim's supplications.
