A vow to slaughter a male sheep, but after slaughtering it, it was found to be female; what is required of him?

Question:
May Allah reward you with good. What is the ruling on one who vowed to slaughter a sheep because of something, and when he bought the sheep from its owner and slaughtered it, he found after slaughtering that it was a goat, not a sheep, and the owner of the sheep said it was a sheep, and at that time he was deceived during the purchase? Does that suffice for the vow, or is the sheep necessary? May Allah reward you with good.

Answer:
It depends on the intention. If he intended the sheep and specified it, then the female does not suffice. But if he did not intend this, but rather intended to slaughter a sheep, and he used the word "sheep" as a reference to the sheep, because some people say "sheep" when they mean the sheep, whether a male sheep or a ewe, meaning a female, then there is no harm in this case. The criterion is the intention. Yes.
