What is halal meat? Is the sheep or goat slaughtered by Christians halal?

It is permissible to eat from animals slaughtered by a Christian or a Jew because of the general implication of the words of God Almighty: "The food of the People of the Book is lawful unto you and yours is lawful unto them" (Quran 5: 5).

Meat that is unlawful for consumption is that which you are certain comes from animals prohibited by the Shari'ah, unslaughtered animals or animals slaughtered by a person who is not from among the People of the Book.
