What is the ruling on one who slaughters with the intention that he is slaughtering for Allah, and then to the spirit of the deceased as charity for him?

Question:
He says: Honorable Shaykh, may Allah grant you success. The questioner says: My grandmother slaughters for the deceased on a specific day. He says: When I ask her why she slaughters, she says, "I slaughter for Allah, and then to the spirit of the deceased, as charity for him." What is the ruling on this action?

Answer:
This is shirk (associating partners with Allah). That is, she slaughters for Allah and for the deceased; all of this is shirk (associating partners with Allah). However, if her intention is that she is slaughtering for the deceased, meaning as charity, slaughtering for Allah and giving the meat in charity for the deceased, then there is nothing wrong with that. She slaughters for Allah, for Allah, and gives the meat in charity, making its reward for the deceased, just as she gives food and clothing in charity; there is nothing wrong with that. Yes. But if she draws near to Allah and draws near to the deceased, then this is shirk. Yes.
