D'var Halacha

  We are beginning siman 10. The Chayei Adam writes that, as we move further in hilchos Shabbos, we must realize that any time the halacha is that one is patur, it means one is patur mideoraysa. However, it does not mean it is muttar, but rather it is an indication that it is assur […]

We are continuing in siman 9. The Chayei Adam is discussing one who begins a large project, such as writing a letter, harvesting a field, or weaving a basket, but only performs a small part of the project. One could mistakenly think that since they have not completed the entire project, it is considered a

We are continuing in siman 9, discussing the concept of performing a partial melacha. The Chayei Adam discusses a caveat given to us by Chazal. We mentioned that one of the ways to perform a partial melacha is to perform the melacha with someone else, such that both people are performing the melacha together. This

  We are beginning siman 9, where the Chayei Adam discusses the concept of performance of a full melacha versus performance of a partial melacha. We left off discussing the difference between the concept of performing a partial melacha, where one is patur mideoraysa, and chatzi shiur, where one is chayav mideoraysa.    The achronim

  We are beginning siman 9, where the Chayei Adam discusses the concept of performance of a full melacha versus performance of a partial melacha. The Chayei Adam writes that another application of this concept is where two people perform a melacha together. For example, two people holding a pen together and writing two letters.

  We are beginning siman 9, where the Chayei Adam discusses the concept of performance of a full melacha versus performance of a partial melacha. One application of this concept is when a melacha has multiple steps to its performance, and those steps are spread out amongst different people. None of those people are chayav

We are continuing in siman 8, discussing the concept of misaseik. We left off discussing whether misaseik is assur on a Torah level or whether it is completely a din derabanan. This question is the subject of a long teshuva by Rav Akiva Eiger, based on a long Tosfos in Maseches Shabbos and Kerisos.  Rav

  We are continuing in siman 8, discussing the concept of misaseik. We need to discuss misaseik within the context of maaseh Shabbos. If a person performs melacha on Shabbos, Chazal place certain limitations on whether the outcome of the melacha can be enjoyed on Shabbos. One opinion in the Gemara is that maaseh Shabbos

  We are continuing in siman 8, discussing the concept of misaseik. We left off with a question regarding when the eruv is down and whether one must inform others that the eruv is down, or are those who carry unknowingly considered misaseik.    Rav Moshe Feinstein and Rav Ahron Kotler bring a proof to

    We are continuing in siman 8, discussing the concept of misaseik. We left off discussing the practical relevance of the concept of misaseik, and whether it only applies after the fact, after something has been done without intention. One relevance of this concept is the question of whether one must take steps to

  We are continuing in siman 7, and we last learned that although melacha she’eina tzricha legufah is derabanan, it does not enjoy the standard leniencies which apply to an issur derabanan. We learned (S277) that, according to the Rambam, melacha she’eina tzricha legufah is deoraysa, and would require a korban when transgressed b’shogeig. However,

  We are continuing in siman 7. We learned (shiur S277) that the Ran says that melacha she’eina tzricha legufah is more chamur than an average derabanan, because it is so similar to the issur deoraysa. One can see two people digging a hole; one person will be transgressing an issur deoraysa and the other

We are continuing in siman 7, where we left off with a question about the interface between melacha she’eina tzricha legufa and psik reisha. This question applies both to psik reisha d’lo nicha lei and to psik reisha d’nicha lei. The impetus behind the question is that the Gemara says that Rav Shimon agrees by

  We are continuing in siman 7, discussing the concept of melacha she’tzricha legufa and melacha she’eina tzricha legufa. The Chayei Adam gave an example of one who digs a hole for the purpose of the dirt rather than for the purpose of the hole.    The Chayei Adam gives another example of one who

  We are beginning siman 7, where the Chayei Adam introduces the concept of melacha she’eina tzricha legufa. This concept is unique to Shabbos, and Rashi explains that this unique halacha is a result of the concept of meleches machsheves.    The Chayei Adam writes that, according to the Rambam, a melecha she’eina tzriacha legufa

  We are continuing in siman 6, discussing the concept of psik reisha d’lo nicha lei. We learned that our accepted psak is that a psik reisha d’lo nicha lei is assur, and that we do not follow the Aruch.    The Chayei Adam continues, and writes that when it comes to psik reisha by

  We are continuing in siman 6, discussing the concept of psik reisha d’lo nicha lei, which refers to a psik reisha in which a person does not care about the result. D’lo nicha lei can include both when a person actively dislikes the result and when they are ambivalent to the result. We learned

We are beginning siman 6, where the Chayei Adam will introduce a caveat to the concept of psik reisha. We know that a davar she’eino miskavein is muttar, but a psik reisha makes it assur and chayav. In this siman, the Chayei Adam further clarifies that the chiyuv is only if a person wants the

  We are continuing in siman 5, and we left off discussing a Rema in Yoreh Deah, where the Rema is discussing a case of pots cooking above the hearth. Although the case does not seem to be a psik reisha, the Rema holds it is assur, even though it should only be a davar

  We are continuing in siman 5. Yesterday, we learned about the concept of psik reisha and how it affects davar she’eino miskavein. In the parentheses, the Chayei Adam explains the meaning behind the choice of the words psik reisha. He writes that just like it is impossible to cut off the head of an
