In a western store I was surprised to see a pack of chicken labeled as halal. Not only was it labeled halal, it was actually certified to be halal. When I looked at the label on the back, the first thing it said was mechanically slaughtered.
This is not only the case in western countries but in the subcontinent as well. A machine slaughters chickens that are hung upside down while a tape recorder repeats Bismillah AllahuAkbar. Sometimes a person may be employed to repeat Bismillah AllahuAkbar. The thing common with both is that the recitation of Bismillah AllahuAkbar is not done simultaneously with the slaughter. Even if it was simultaneous, the chicken would still be haram. Chicken has to be slaughtered by hand.
There is a lot of ignorance concerning halal. I have seen a pack of fish nuggets labeled as halal. Since when was fish required to be slaughtered?
There is a true story of a Muslim who was served pork in an American restaurant. Upon inquiry the waiter replied, “Yes it is pork, but don’t worry Sir, it is halal!
