Praise be to Allah.
The Muslim has to be careful with regard to this matter, and try to ensure that his food, drink and clothing are halaal. It is well known that meat slaughtered by idol-worshippers such as atheists and Sikhs etc., who are not Jews or Christians, is not permitted for us to eat.
One of us Muslims could do the actual slaughtering, and then hand the carcass over to someone else to skin it and cut it up.
Written by ‘Abd al-Lateef.
If it is slaughtered by a Muslim or one of the People of the Book (a Jew or Christian), that is fine. If it is slaughtered by someone else, then we should not eat it. If it is slaughtered in an abattoir where there are followers of various religions, including Muslims, Christians, Buddhists, Hindus, Communists and apostates from Islam, and it is not known who has slaughtered the meat that is on offer, then it should not be eaten. And Allaah knows best.
