Rav Yisroel Belsky ztl writes In olden times, the very greatest medakdekim b’mitzvos, those Jews who were exceedingly meticulous in their observance of mitzvos, were careful never to sit on cushions or mattresses made from shredded fibers. It was a very big chumrah for two reasons. Firstly, there was only a very slight possibility that these cushions and ...

There are multiple options depending on how much of a reference book you are searching for vs. something which is readable cover-to-cover to rehearse. The 39 melochos is an amazing reference work but it is very heavy (ca. 2000 pages) and detailed. Serves best to check out or learn in depth a specific melacha with Hebrew footnotes to enable further study ...

In the English version of Shemirath Shabbath k'Hilchata (11:10), R' Yehoshua Neuwirth is strict and writes: When removing the shell from an egg, one should be careful not to break through any letters or designs which may be stamped on it. but he is most likely speaking of hand-removing the shell while your case is slightly different. I believe that, ...

Rabbi Yaakov Kamenetsky and the Moon landing אמת ליעקב פרשת בראשית ודברי רמב"ן אלה הם שעמדו לי בשעה שראינו איך שבני אדם יורדים מעל המטוס ע"י סולם על גלגל הלבנה, וחשבתי בלבי מה יענה כעת הרמב"ם ז"ל שכתב שהלבנה היא בעלת צורה רוחנית, והרהרתי בלבי שכעת נצחה הקבלה את הפיליסופיא, ונחמתי את עצמי בדברי רמב"ן אלו. אבל כפי שאנחנו מתייחסים לדברי הראשונים ...

Revised psak can be three different things. 1) A Rabbi or Beis din, realizes they made a big mistake. (certain pigs are kosher ... ooops! wrong) So after the psak (legal decision) is issued (example: that pigs are kosher), the Rabbis issue a public recall and say "We made a grave error in judgment. It was a mistake. All should know that pigs were never ...

Piskei Shabbas by Rabbi Eliezer Padwar is also very helpful sefer. It is 4 volumes (Yom tov as one vol) . It is in English and has footnotes.

The 39 Melochos by Rabbi Dovid Ribiat. I haven't used it that often myself, but in my experience of observing others this seems to be one of the most, if not the most, highly regarded English books about the laws of Shabbos. The few times that I have used it it seemed to do a good job of laying out the concepts and providing the relevant sources.

Yes, idolatrous items contaminate, and things that get mixed with objects of idolatry are forbidden property. However, these are two separate laws. The Rambam has already said that objects of idolatry are forbidden in benefit from the Torah (Hilchot Avodat Kochavim 7:2). Therefore he explains here that once an object of idolatry is mixed with or lost among ...

Radzyner Techeiles Radzyner techeiles is made from the "ink" that is secreted from the Sepia Officinalis, i.e. the common cuttlefish. The Radzyner Rebbe, R.

He wrote a short book called Sefunei Temunei Chol in which he outlines 10 criteria for identifying ...

The Lubavitcher Rebbe's reaction from Chabad.org: Yes, the human being has performed something magnificent. There is much in which to take pride. But does that make us so large as to displace G‑d? Just the opposite! We only know the greatness of the Creator from the greatness of His creations. Now that we see He has created a being that is capable of ...

dinonline (here and here) answer a very similar question Before getting into the technical halachic aspect if it is permitted or not, it is surely not advisable to stay there when you are prone to looking at idolatrous images on a constant basis.

The Rambam (in Hilchot Mechira 25:5) brings the following halacha When a person sells a house, he also sells the oven, the range, the door frames that are attached with mortar, the door, the beam, the lock, but not the key.

I can't say that all Kosher meat processors follow the same process but some use a "picker" machine which works with agitation of the chicken against small rubber parts that de-feather it but still keep the chicken intact. FYI, one can buy a drill attachment that is a chicken plucker for home use so one can avoid scalding.

Not sure if just saying someone is stupid is Lashon Hara, it depends on the context and how it's said. But in general, when slandering to a Gentile, besides the sin of speaking slander about your fellow man, you are also desecrating the name of God by bad-mouthing his children.

The sefer “Ashrei Ha’Ish” contains the rulings of Rabbi Yosef Shalom Elyashev z”l.

The Sefer gives an example of a repair ...

The disagreement with these devices(disregarding light bulbs in fridges or fans in ovens, at the moment) is whether grama or pesik reisha d'lo neicha lei are permitted on shabbat; assuming we accept the notion that using these devices on shabbat do not contain the issue of boneh, makeh b'patish, bishul, or mav'ir(see Yechave Da'at 1:32; Tzitz Eliezer 6:6; ...

The following question was asked at “din.org.il”: האם יש איסור באכילה עם גוי על שולחן אחד? ואם כן האם יש נ”מ בין קביעת סעודה על לחם לשאר אוכלים?

Many Rabbis say it is indeed a problem at weddings. Rav S.Z. Aurbach and Rabbi Scheinberg who are quoted as saying weddings are not an issue, is because the removal of the bread/tables was not because they are in fact done with the bread, but rather for a different reason, the dancing. See the picture from the Dirshu Mishna Berurah below. But certainly when ...
