Chapter 127 : Chapter 127 Laws Concerning Private Fast Days
§1
Just as it is a mitzvah for the community to fast and to pray in times of trouble, so it is a mitzvah for every individual, if, God forbid, any trouble befalls him, for example, a member of his family is sick, or he lost his way, or he is confined in prison on false charges, to fast and to pray to God, and to plead for mercy from Him, may His Name be blessed, to deliver him. Suffering is one of the ways that leads to repentance. A person should not say, his troubles just happened by chance, for it is said: (Leviticus 26:23,24). "If you treat My (acts) as chance, then I will treat you with the fury of chance"; which means, when I bring distress on you to cause you to repent and you will say this happened by chance, then I will add to your (suffering) the fury of the same "chance." Man must know that because of his sins, God brought on him all this trouble. He should, therefore, examine his deeds and return to God, and He will have mercy on him.
§2
If you wish to fast, you must make a commitment to do so on the preceding day, during the
Shemoneh esrei of
Minchah. In the berachah
Shema koleinu [Hear our voices], you should mentally accept upon yourself, to fast and before saying
Yiheyu leratzon, you should say, Master of the universe, I come before You to accept a fast etc. (as it is written in the
siddur [prayer book].) Even though you eat and drink, afterwards until daybreak, it does not matter. If you want to fast several days in succession, although you will eat and drink during the intervening nights, one acceptance [commitment] is sufficient for all. But if you accept upon yourself [to fast] several days that are not in succession, like Monday, Thursday, and Monday, you should make a separate commitment, for each day you fast, in the
Minchah preceding it.
§3
If you are accustomed to fast during the
Aseres yemei teshuvah, [the Ten Days of Penitence] or on the first day of
Selichos or on
erev Rosh Hashanah, you do not have to make a formal commitment because they are accepted on the basis of the prevailing custom. Similarly, fasting because of a disturbing dream, does not require prior acceptance; neither do the fasts on Monday, Thursday and Monday following
Pesach and
Sukkos. If you answer
Amein after the
Mi shebeirach [a blessing for those who fast on these days] and you intended to fast, this is sufficient, and no other form of acceptance is needed. Nevertheless, if you change your mind, and do not wish to fast, you may [eat], since you did not expressly commit yourself and did not verbally declare that you intend to fast.
§4
Even if you did not commit yourself verbally, to fast; doing so, only in your mind, resolving to fast the following day, and even [if you made this resolution] not during
Minchah, but either before or after
Mincha, while it was still daytime, it is considered an acceptance, and you are required to fast.
§5
When you fast, you should not indulge in enjoyment, nor act frivolously. You should not go around happy and cheerful, but rather with anxiety and sorrow, as it is said: "Why should a living man bemoan? A man, because of his sins!" (Lamentations 3:39).
§6
On a private fast day, you are allowed to rinse your mouth with water, in the morning.
§7
If you committed yourself to fast without being specific, you must complete the fast until the stars come out, even on
erev Shabbos.
§8
If someone fasts and publicizes the fact, bragging about it, he will be punished for it. But if people urge him to eat, he may let them know that he is fasting.
§9
If you observe a fast, even if it is a private fast, whether it is a voluntary fast, or a fast because of a disturbing dream, you should say in the
Shemoneh esrei of
Minchah, in the berachah
Shema koleinu [Hear our voice], the prayer
Aneinu [Answer us], the same as on any public fast day. (And although you are only one individual, you should say it in the plural, and not deviate from the formula, that was established by the Sages). Before saying
Yiheyu leratzon, you should say
Ribbon ha'olamim [Master of the universe] etc.
§10
If you vowed to fast one day or ten days, but you did not specify the particular day or days, on which you were going to fast, but you stated it in indefinite terms, even if you committed yourself in the
Minchah prayer to fast the following day, if an urgent need arises for you to eat something, for example, if you are invited to a meal, that is considered a mitzvah, even though you are not a party to the festive meal; or an important person urges you to join him in a meal, and it is difficult for you to refuse him, or if you do not feel well [enough to fast], then you may "owe" the fast [and repay it later] and you may eat on that day, even if you already began to fast, and instead of fasting that day, you should fast another day. This is permissible only if the fast, you had accepted on yourself, was meant to fulfill a vow, however, if you had made no vow, but (specifically) committed yourself during
Minchah to fast the following day, then, even if it causes you great distress, you are not permitted to "owe" your fast and repay it another day.
§11
If at the time you made the vow, you specified certain days, and you also accepted it on yourself during
Minchah, you may no longer "owe" your fast (to be paid later.).
§12
If you undertook to fast, and are experiencing grave discomfort because of it, you may redeem it with money, according to your means, and you should give the money to the poor. But for a fast in fulfillment of a vow, redemption is of no avail. On a fast day, decreed by the community, redemption is also of no avail, unless the community made such a stipulation.
§13
If you made a vow to fast on Monday, Thursday and Monday, you may change it to fasting on Thursday, Monday and Thursday, but not to any other days (of the week), for it is presumed, that you had these days in mind, because they are the days when the court is in session.
§14
If you fast on Monday, Thursday, and Monday following
Pesach and
Sukkos, as well as on the
Aseres yemei teshuvah, [the Ten Days of Penitence], and you did not commit yourself to fast during
Minchah, but your fasting is motivated by the custom, even if you had in mind to fast, when responding
Amein to the
Mi shebeirach, as long as you did not resolve to fast during
Minchah, then, if there is a
bris [circumcision] or a
pidyon haben [redemption of first born male] or any other meal celebrating a mitzvah, you are fulfilling a mitzvah by eating, and you need not absolve your vows, for whoever fasts on these days is following the rules imposed by custom, and this custom of fasting was not intended in regard to a meal in celebration of a mitzvah.
§15
In cases, where you are permitted to eat at a meal celebrating a mitzvah, the fast is, thereby, ended altogether, and you may eat afterwards, even in your own house; but before the festive meal, it is forbidden to eat. Only the father of the infant on the day of the
bris and the
sandak may eat even before the meal, since to them it is like a Yom Tov.
§16
However, if you ate on a fast day in violation of the law, whether inadvertently or intentionally, you must complete the fast, even after having eaten. Afterwards, you must fast on Monday, Thursday and Monday, as an atonement for eating on the fast day. It is certainly true that you must fulfil your vow at a later time if you had to fast because of a vow you had made.
§17
If you fast because of personal trouble, and the trouble passed, or if you fast for a sick person, and that person recovered or died, you must complete all the fast days that you committed yourself to observe. If someone accepted upon himself to fast or to do some other mitzvah until his son becomes Bar Mitzvah, and the son died before that time, he must, nevertheless, fulfill his vow until the time his son would have become Bar Mitzvah. However, if you find out that before you committed yourself to fast, the cause for fasting had already passed and your commitment, thus, was made in error, then you are not required to complete it.
§18
Fasting is beneficial when accompained with repentance for nullifying the portents of a bad dream, just as fire consumes the refuse of flax; but only if [you fast] on the day [you had the dream]. However, you are not required to fast, for (the Amora) Samuel said: "Dreams speak falsehood," (Maseches Berachos 55b). You are, however, required to repent and to devote the entire day to the study of Torah and in prayer. Concerning fasting on Shabbos for a worrisome dream, see
Orach Chaim, chapter 288.
