What animals and foods are forbidden in Islam, and is turkey among them, and what is the reason for the prohibition?

The basic principle regarding animals is permissibility. Forbidden among them are pigs, domesticated donkeys, mules, and any predatory animal with fangs or any bird with talons. As for foods, forbidden are anything harmful to the body or mind, based on the Prophet's (PBUH) saying: "There should be no harm nor reciprocating harm," or anything that is vile, based on Allah Almighty's saying: "And He makes lawful for them the good things and prohibits for them the vile things." The turkey is permissible because it remains within the basic principle of permissibility.
