Masjid Ibrahim

In order to diminish the hardship facing Muslims, Allah S.W. made it permissable for Muslims to eat the meat of Islamically allowed animals slaughtered by Jews and Christians with the condition that their way of slaughtering must conform with the Islamic way of slaughtering.

As for the seller of meat, there is no difference whether he/she is a Muslim, a Christian, a Jewish or an unbeliever. However, it should be noted that if the person doing the slaughtering happened to be an idol worshipper, a hindu, or an theist the meat becomes forbidden regardless of the religion of the seller.
