Eating from a sheep vowed as a sacrifice

Question:
The Shaykh (may Allah preserve him) says: If a person reaches the point where he slaughters a sheep and testifies that Allah will make it appear, is it permissible for him to take any of it?

Answer:
If he intended to eat from it, he may eat; he may eat what he intended. If he did not intend to, it is not permissible for him to eat from it. If he spoke and said, "I will eat from it," or if he intended it in his heart without speaking, he may eat from it. However, if he did not intend to eat and did not speak about eating, he is required to give all of it to the poor. Yes.
