- Our kuffar neighbors and colleagues give us food on their holiday periods such as birthdays and christmas. Is it permissible for us to accept it and eat it?
- My non practicing Muslim in laws celebrate birthdays. They share with us slices of that cake. Can we eat from it?
There is a Fatwa from sheikh Jamal Al Harethy, abu Forayhan, regarding your question:
If the food was on a kufr or Bidah occasion, then you should refuse taking it. Because taking it means your approval. So of course in case of christmas, it is Haram to share or to congratulate in any way.
You should also refuse to take during the bidah of celebrating the Prophet’s peace be upon him birth, you have to deny these celebrations.
If it is celebrating people’s birthdays, this is a lesser degree of bidah yet it is wrong. However, the sheikh says that you can take it but you still need to advise that this wrong , but it is better and more pious to refuse taking any of this food.
