If one vows a sacrificial animal without specifying a recipient, is it required to distribute it to the poor?

Question:
He says: Honorable Shaykh, may Allah grant you success, if someone vows and says, "If such and such happens to me, I will slaughter a sacrificial animal," and he leaves it unspecified and unrestricted, is he allowed to direct it wherever he wishes?

Answer:
He may direct it wherever he wishes, but the slaughter is obligatory. If he does not slaughter, he must slaughter a sacrificial animal. If he did not specify a particular benefit, he should distribute it to the poor. Yes.
