What is required of one who swears an oath or makes a vow not to return to a sin, but then returns to it?

Question:
The questioner, whose name is indicated by the initials (S. A. D), says in this question: Your Eminence! I am a man who committed violations on one occasion, and afterwards I regretted it, and I swore an oath, saying: I have sworn, and I vowed to pay a sum of money to the poor if I committed that violation. And I actually committed it again. So, is it obligatory for me to pay the aforementioned money? Or is the expiation for an oath sufficient? May Allah reward you with every good.

Answer:
It is obligatory for every Muslim man and woman, if he commits any of the sins, to hasten to repentance. This is the obligation of every Muslim: to hasten to repentance when he commits a sin. For Allah, Glorified and Exalted is He, says: [An-Nur: 31]. And He says, Glorified and Exalted is He: [At-Tahrim: 8]. This is the obligation of every Muslim man and woman: if a sin occurs from him, he should hasten to repentance and rush to it. Whether it is drinking an intoxicant, undutifulness to parents, usury or interest, unlawful sexual intercourse, or anything else. Whenever a sin occurs from him, he should hasten and rush to repentance, regret, ceasing the sin, and resolving not to return to it, along with increasing in righteous deeds, as Allah the Exalted said: [Ta-Ha: 82].
And if he swears or vows that if he returns to it, he will give such-and-such in charity, or pray such-and-such, or fast such-and-such; then there is a detail in this. If he intended by this to draw near to Allah, and that whenever he commits it and returns to it, he will repent and draw near to Allah with this as an addition to his repentance; then this is obligatory for him. Because the Messenger (peace and blessings be upon him) said: .
A vow of obedience is obligatory to fulfill, due to this authentic hadith: It is obligatory.
As for if he intended by this to restrain himself when he said: I have vowed upon myself that if I disobey, I will give such-and-such in charity, or fast a month, or such-and-such... his intention is to restrain himself, to frighten himself so that he does not have to fast or give charity. He did not intend to draw near to Allah; rather, his intention was to prevent himself from this sin. If he returns to it, then he must repent, and he must pay the expiation for an oath for his vow. Because he did not intend to draw near to Allah with this; he intended to prevent himself and restrain him from this thing. So, in this case, the expiation for an oath is required: feeding ten poor people, or clothing them, or freeing a slave. If he is unable to do so, he fasts three days. And feeding the ten: for each one, it is half a sa' (a dry measure of about 3 kg) (one and a half kilograms) of the staple food of the land, or a garment, such as a shirt, or an izar (lower garment) and a rida' (upper garment). This is what is obligatory for the one who does this. Yes.
