Question: Is it permissible to eat from the meat which has been slaughtered for the occasion of [celebrating] the birthday of the Prophet ﷺ?
Response: No, [celebrating the birthday of the Prophet ﷺ] is an innovation. This is an innovation and an innovated celebration, and that which is slaughtered for the occasion of an innovated celebration is haraam. And the food which is prepared for it is also haraam. That is because it was only done for the sake of keeping the innovation alive and honouring the innovation. And [as such] it is not permissible to take part [in this celebration] with them and nor to eat their food, and nor to eat their sacrifice on this day. That is because this is [tantamount to] encouraging them, and aiding them, and acknowledging [validity] for this innovated practice.
