Ashkenazi eating at Sefardi's House
Q: I am Ashkenazi. Is it permissible for me to spend Seder night at the house of a Sefardi, who eats Kitniyot?
A: Yes, but don't eat Kitniyot. It is permissible, however, to eat: food which touched Kitniyot, food which absorbed Kitniyot, food in which the Kitniyot are no longer recognizable and are nullified in a majority, and food cooked in Kitniyot pots and pans (Shut She'eilat Shlomo 3:141).
Breaking a Glass under the Chuppah
Q: Why do we break a glass under the Chuppah?
A: A Remembrance of the destruction of the Temple in order to show that our joy is still incomplete. Berachot 31a. Shulchan Aruch, Orach Chaim 560:2.
Q: Should the glass be expensive or perhaps inexpensive to avoid "Bal Tashchit" (wantonly destroying items)?
A: An argument can be made both ways: Expensive to bring a bit of sadness, or inexpensive to avoid "Bal Tashchit". Sedei Chemed, Asifat Dinim Marechet Zayim #12. One should therefore take a regular glass. Shut Yabia Omer 4:19.
Selling Chametz over the Internet
Q: Is it possible to sell Chametz over the internet?
A: Yes. It is a form of appointing an agent.
Precedence in Granting a Furlough
Q: I am an officer in Tzahal. If I am able to grant some of the soldiers a furlough, should I give precedence to married soldiers?
A: Definitely. A married soldier has a great need (see Shut Keshet Nechushah Vol. 1, p. 136).
Wrapping the Tefillin
Q: When one wraps the Tefillin around his arm 7 times, do 2 half loops combine and count as one of them?
A: It is a dispute (Petach Ha-Dvir 27:2. Kaf Ha-Chaim 27:35).
Hand-Made or Machine-Made Matzah
Q: According to Ha-Rav Tzvi Yehudah Kook, which is preferable: hand-made or machine-made Matzah?
A: Our Rabbi was particular to use machine-made Matzah since it was decided by the halachic authorities that machine-made Matzah is Kosher, and there is, in fact, greater care regarding the concern of Chametz than with hand-made Matzah (and once when our Rabbi was asked this question, he answered: In the same amount of time that we exert ourselves to make one hand-made Matzah it is possible to make Reb Noson’s [our Rabbi’s brother-in-law], his own and many other people’s Matzah for the entire holiday).
Q: Should one sign up for the Korban Pesach in anticipation of the coming of the Mashiach?
A: No. There is no need. We anticipate the coming of the Mashiach every day, but the building of the Temple will not be today. See Rambam, Melachim 1:2.
Davening in the Wrong Direction
Q: If I began Davening in the wrong direction, i.e. not towards Yerushalayim. May I turn around?
A: Yes, walking for the needs of Davening without speaking is not considered an interruption (Mishnah Berurah 104:2. Piskei Teshuvot ibid.).
