The Issue

Muslims may live in non-Muslim countries where the local population are unbelievers who do not follow any divine religion, as in the case of idolaters, atheists, Zoroastrians, etc. Can they eat of the meat of animals slaughtered by such unbelievers?

Ruling

A Muslim may not partake of the meat of animals slaughtered by unbelievers other than the followers of earlier divine religions. This applies to Zoroastrians, idolaters, atheists and the like. Nor is it permissible to eat of their food that is mixed with such meat, including the sauce. The only exception is the case of absolute necessity that permits eating carrion. This ruling is issued by the Permanent Committee for Research and Fatwa in Saudi Arabia, and it is endorsed by Shaikh Abd al-Azeez ibn Baz.[1]

Evidence

God has only permitted us to eat the food of the followers of earlier divine religions.

According to Ibn [Abbas and others, the food the verse refers to is their slaughtered animals. Other unbelievers are not included in this permission, which means that their food is forbidden to eat.
