Kosher and Halal are both ritual laws used by both Jews and Muslims. While the two terms are similar in some ways, most especially in terms of meaning, there are, however, some differences between the two. One of the major differences between the two words is that Kosher is a term commonly used by Jews, while Halal is an Arabic term.
In terms of meaning, both terms are the same; they mean something permissible, fit, or proper. The religious activities that surround the usage of the two terms is another difference. For instance, Kosher, which can also be regarded as a food law, allows Jews to pray only on the first and last animals when slaughtering them.
In contrast, Muslims are religiously bound to call the name of God on every animal to be slaughtered. In Kosher, animals can only be slaughtered by a Rabbi known as the Sachet. In contrast, Halal allows the slaughtering of the animal to be done by any adult Muslim.
