All agree that when Erev Shabbos is Rosh Chodesh Menachem Av, one who washes every Friday with hot water, soap, and shampoo, may do so this Erev Shabbos also.
When making the berachos over the Torah upon receiving an aliyah, care must be taken to make the berachah loudly. If less than 9 adult males hear the berachah, it is very questionable if it is valid. If at least 9 adult males hear the berachah, everyone may respond–together with them—”baruch HaShem hamevorach…”
If less than 9 heard, no one may respond “baruch HaShem…” nor may anyone answer “amein.”
- On a fast day, if the chazzan forgets the beracha of “aneinu”, if he did not yet say the Name of HaShem at the conclusion of the beracha of refa’einu, he should go back to aneinu. If he did say that shem haShem, he should continue and say “aneinu” in “shome’ah tefillah”, BUT he should conclude the birchas shome’ah tefillah in its usual way.
- An individual, at Minchah. who forgot “aneinu” and concluded shome’ah tefillah, should continue and say “aneinu” during “Elokeiy, netzor…”. If he does not say it there, either, shemoneh esrei is not repeated.
It is better to daven with a small minyan in a Beis Medrash (where people regularly learn Torah) than with a larger minyan in a Shul (if they don’t learn Torah). This is learned from the passuk “HaShem loves the gates of Zion (gates that learn Torah. see Gemara Berachos 8a and Shulchan Aruch O.C. 90:18 with MB there which explains the derasha) more so than all the dwellings of Yaakov (the Shuls)” (ibid).
Of course, BTYA is best of all!
When there is an aufrauf AND a bar-mitzvah in a Shul on the same Shabbos, the minhag developed to give the bar-mitzvah boy maftir, with the chosson getting the Aliyah before maftir.
But the truth is that this minhag developed at a time when a bar-mitzvah was celebrated the Shabbos BEFORE the bar-mitzvah–and thus maftir was the only aliyah that the bar-mitzvah boy COULD get!
