I vowed before I reached puberty that if my father were healed, I would fast nine consecutive days. Is fasting obligatory, and is consecutiveness obligatory in the fasting?

Question:
She says in her question: My uncle and my father were afflicted with the same illness, and it has been years since they fell ill, as Allah knows. I vowed that if my father were healed before the month of Dhul-Hijjah, I would fast from the first of Dhul-Hijjah until the day of the festival, that is, ten or nine days. At that time, I had not reached puberty. My father was healed, praise be to Allah, before the month of Dhul-Hijjah. Three years have passed since his healing, and I have not fasted anything. I say that I was not accountable when I made the vow, even though I was capable of fasting, praise be to Allah. I ask you to clarify this matter regarding whether fasting is obligatory upon me, and whether I can fast whenever I wish? Is consecutiveness obligatory in the days of fasting for the vow? May Allah reward you with good.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds. May Allah send prayers and blessings upon our Prophet Muhammad, and upon his family and all his Companions. As for what follows, according to what the questioner mentioned, she had not reached the age of accountability when she made the vow. Therefore, this vow is not obligatory upon her, because a vow is only binding upon a person of legal capacity, that is, an adult who is of sound mind. Since she had not reached puberty, nothing is required of her regarding what she mentioned. Yes.
