What is the ruling on eating the food of the People of the Book if it is for an occasion of theirs, such as their celebration of Christmas or others?

The questioner : The food of the People of the Book is lawful for you, on the basis that it is lawful. The food of the People of the Book, if you know that the food of the People of the Book, or a specific meal at the People of the Book, has religious rituals, like, for example, Christmas or Thanksgiving, and these things on this day, if you know that this meal is for this occasion, is it permissible for us to eat from this meal or not?

The Shaykh : No, and it is not permissible to support the disbelievers in their religious customs, whatever their forms and appearances may be, whether food, clothing, or celebration. All of this is not befitting and is not permissible. "The food of those who were given the Scripture" means the usual eating, if it is a lawful slaughter, otherwise not. Here, let us see what you have?

The questioner : I have a peace offering, God willing.

The Shaykh : It is all good, as long as it is not from that good.
