The ruling on one who slaughters at a grave believing that it is superior

Question:
May Allah be merciful to you, Your Eminence, father. The questioner says: If a man slaughters an animal at a grave, thinking that it is better than slaughtering in his house, is this considered shirk (associating partners with Allah)?

Answer:
If he intends to honor the deceased and draw near to him, then this is major shirk. But if he slaughters at the grave, thinking that slaughtering there is better, and he does not want anything but Allah the Exalted and Majestic—he slaughters for Allah, but he thinks that slaughtering at the grave is superior, and he does not want the grave itself, only the place—then this is bid'ah (religious innovation) and a means to shirk; bid'ah and a means to shirk. Yes.
