I called the ButterBall Hotline and asked the nice lady who answered of the Butterball was Halal. She said yes. I asked if that means if a Muslim prayer was said over every turkey. She got flustered and looked up a corporate boiler plate text saying yes that the butter ball met hallal standards and that it was humane and holesome.
I said that ok but the question about the prayer wasn’t answered. She said she would find out.
I said that’s a good idea because they were going to get a deluge of calls about this and you’d better get it right.
That question came up last night on FR. Every Islamic source I can find, and I looked onto Halal certification websites, say that a prayer to Allah must be said for it to be Halal.
My understanding is that it is permissible to have a continuous loop playing while the animals are slaughtered in accordance with Islamic rules.
