If a sacrifice is offered on behalf of a deceased father, must his heirs refrain from cutting their nails until the sacrifice is offered for their father?

Question:
He says: Honorable Shaykh, may Allah grant you success, my father passed away (may Allah have mercy on him), and we are now offering a sacrifice on his behalf. Is it permissible for my mother to cut her nails, and likewise, is it permissible for the rest of the heirs to cut their nails?

Answer:
If they are sharing the sacrifice, meaning each person who is being sacrificed for is sharing in it, then no, the one who is being sacrificed for does not refrain. The correct view is that the one who refrains is the one who slaughters the sacrifice, the one who pays for the sacrifice from his own wealth, whether for himself or for himself and others; he is the one who refrains. As for the one for whom the sacrifice is offered, this is not mentioned in the hadith . As long as he is not the one who pays for the sacrifice and slaughters it from his own wealth, there is no harm in his cutting his nails. It is only the one who will slaughter it from his own wealth who refrains. Yes.
