Question: If, after davening Mussaf on Rosh Chodesh, one realized that he
forgot to recite Ya’aleh v’Yavo during Shacharis, is he required to repeat
the Shacharis Shemoneh Esreh?
Discussion: The poskim are divided in their opinions as to whether or not
one needs to repeat Shacharis in this case. The proper procedure, therefore,
is to repeat the Shemoneh Esreh while stipulating (in advance) that in case
this Shemoneh Esreh is not obligatory, then it should be considered a
tefillas nedavah, a voluntary prayer. [Although generally we avoid
davening a tefillas nedavah due to our deficient kavanah, in this case,
where many authorities require the Shemoneh Esreh to be repeated, we may
make the above stipulation. ]
Question: If one forgot to daven Mussaf (on Shabbos, Rosh Chodesh or Yom
Tov) and only remembered to do so in the afternoon, which should he daven
first — Mussaf or Minchah?
Discussion: In most cases, Mussaf should be davened first, followed by
Minchah. This is because the correct order of the prayers follows the order
of the sacrifices that were brought in the Beis ha-Mikdash, and the Mussaf
Sacrifice was always brought before the afternoon Korban Tamid, which was
the last offering of the day.
[The only exception to this halachah is the case of a person who is
required to daven Minchah at that particular time, e.g., before partaking in
a wedding or a Sheva Berachos meal. In such a case, since one is not allowed
to partake of such a meal before davening Minchah, it is considered as if
the time of Minchah has arrived and one should not daven Mussaf first. ]
The halachah remains the same even if a man remembered to daven Mussaf so
late in the day that he would not have time to daven Minchah any longer. He
should daven Mussaf, and then daven Ma’ariv twice, first as Ma’ariv and the
second as a tashlumin (“makeup”) for Minchah. If this happened to a
woman, however, she should daven Minchah and omit Mussaf, since she is
obligated (according to most poskim) to daven Minchah and it is questionable
whether she is obligated in Mussaf altogether.
Question: Are women obligated to observe the custom of refraining from
“working” on Rosh Chodesh?
Discussion: The custom that women refrain from doing certain types of work
on Rosh Chodesh — both by day and by night — is an age-old custom,
dating back to the days of Moshe Rabbeinu, which is recorded in the Rishonim
and Shulchan Aruch and should be upheld by all girls and women. Whenever
possible, women should not do “work” on both days of Rosh Chodesh, but if
one cannot refrain from doing work on both days, she should do her “work” on
the first day and refrain from working on the second. See follow up
Discussion for the definition of “work.”
Question: Regarding the custom for women to refrain from “working” on Rosh
Chodesh, what is considered “work”?
Discussion: Over the centuries, various customs evolved as to exactly what
is considered “work” vis-à-vis Rosh Chodesh. Nowadays, women generally
refrain from sewing, crocheting and doing laundry on Rosh Chodesh. Ironing,
however, is permitted.
Some poskim hold that using a washing machine is permitted, and only
washing by hand is prohibited. Others are more stringent and prohibit
laundering in washing machines as well.
