Abrahamic religions teachings of Quran are presented as the direct revelation and words of Allah. Islam (meaning "submission", in the sense of submission to God) is universal (membership is open to anyone); like Judaism, it has a strictly unitary conception of God, called "tawhid", or "strict" or "simple" monotheism. Historically, the Abrahamic religions have been considered to be Judaism, Christianity and Islam. Some of this is due to the age and larger size of these three. The other, similar religions were seen as either too new to judge as being truly in the same class, or too small to be of significance
Abrahamic religions permitted food known as kosher in Judaism, and halal in Islam. These two religions prohibit the consumption of pork; Islam prohibits the consumption of alcoholic beverages of any kind. Halal restrictions can be seen as a modification of the kashrut dietary laws, so many kosher foods are considered halal; especially in the case of meat, which Islam prescribes must be slaughtered in the name of God. Hence, in many places, Muslims used to consume kosher food. However, some foods not considered kosher are considered halal in Islam. With rare exceptions, Christians do not consider the Old Testament's strict food laws
