The ruling on one who vowed to slaughter an animal if his brother was healed but did not fulfill his vow

The questioner:
Peace be upon you, O Shaykh.

The Shaykh:
And upon you be peace.

The questioner:
If you please, Shaykh, I have a brother who is sick with a headache, and I said, I said, if his headache gets better this month, I will make a vow, meaning I will slaughter a sacrificial animal and invite four workers and four people from the village to it, and I did not fulfill the vow.

The Shaykh:
Meaning, the sick person was healed.

The questioner:
Yes, it got better, yes, it got better for him.

The Shaykh:
Yes, fulfill your vow. Whoever vows to obey Allah, let him obey Him. Fulfill your vow: slaughter the animal and distribute it to the people you designated for it.

The questioner:
Okay, Shaykh, is it okay if I just buy food for the four people instead? Ten poor people, or four?

The Shaykh:
No, no, you must slaughter. You must slaughter, you vowed to slaughter a sacrificial animal.

The questioner:
Slaughter a sacrificial animal and cook it, is it okay if I distribute it to them? I just slaughter it.

The Shaykh:
Do you distribute it to them as meat, or cooked? According to what you said, you said you would distribute it cooked, or do you distribute it as meat?

The questioner:
I left it for cooking.

The Shaykh:
Yes, cook it and distribute it to them as cooked meat.

The questioner:
But I told them I would bring them to my place for a meal.

The Shaykh:
Do you bring them to your place, or do you give it to them? How?

The questioner:
No, I vowed that I would bring them to my place and put them at the table, four people. Okay, do I carry this cooked food and give each of them a portion that is enough for them?

The Shaykh:
Yes, yes, it is all one thing: do you bring them to your place, or do you give it to them.

The questioner:
Meaning, the most important thing, the most important thing is to intend that the vow is for cooked food.

The Shaykh:
No, you must fulfill the vow as you vowed it, yes.
