Which is the food of the people of the book that has been made permissible in Surah Al-Maidah for Muslims?

If it is slaughtered. Slaughter of people of the book, which are Christians and Jews. If they chop the head completely, is it acceptable? If a Muslim chops the head completely, is it acceptable? It is not preferable, but that does not invalidate the slaughter.

Sometimes we understand that pumping out the blood of the animal is essential for animal to be halal. If we go for hunting and shoot the deer and say Bismillah before shooting it, and the deer drops dead, can you eat that? Yes, but what happen to the blood? It is not the issue of the blood, you can cut the animal etc., but there will be various circumstances in the reality. And it is not the primary issue of halal and haraam. As long as the animal is slaughtered and said Bismillah before it, whether you cut the head completely or only the food and wind  pipes, it is still permissible to eat.

People of the book got a special treatment among other disbelievers, because even if their current holy book is deviated, but it still contains revelation in it.
