Islam places great emphasis in the way in which an animal’s life ends, which has to be in accordance with Islamic regulations. Life is a sacred blessing of God to creation, animals as well as humans.
If the life of an animal has to be ended for human survival, then its life should only be taken in the name of God. Hence, the phrase bismillah (‘in the name of God’) must be uttered just before slaughtering an animal.
Muslims cannot consume the meat of animals that are sacrificed in a name other than God. Any animal slaughtered in the name of a person alive or dead, any deity or idol will be considered as haram and therefore it is not permissible for Muslims to consume that meat.
