Definition
- Separating any two objects that are glued or sewn together is considered an act of tearing, Koreah.[1] However, this is only an issue if they were attached with at least some permanence.[2]
- For example, it’s permissible to open an envelope or a booklet that was stapled shut just for transmission by post by removing the staples. However, it’s forbidden to remove the staples from two papers that were stapled together permanently.[3]
Separating pages of a book
- It’s forbidden to cut or rip pages of a book that were not properly cut through in binding. [4]
Toilet paper
- Toilet paper or paper towels may not be ripped along perforated edges or not along perforated edges on Shabbat.[5] Some say in a situation where there’s no other option it’s permissible with a shinui (such as ripping with one’s elbow). [6]
- According to Sephardim, one should really rip toilet paper before Shabbat, however if one didn’t then, it’s permissible to rip in order to wipe yet one may not rip on the perforations and preferably this should be done with a shinui (like with one’s foot).[7]
- Tissues or wipes that are slightly connected in order to facilitate that one tissues pulls out the next tissue or wipe out of the box, one shouldn't use these tissues or wipes on Shabbat.[8]
Practical Examples
- Regarding removing the plastic tabs from the band aid edges, see Medicine on Shabbat.
- It is permitted to separate the sides of a diaper from the back panel even though it is minimally connected since that wasn't connected intentionally or for a permanent connection.[9]
- It is permitted to open a garbage bag of which the folded edges are connected and perforated.[10]
- Ripping a piece of tin foil on Shabbat is forbidden.[11]
Opening Mail
- It’s forbidden to tear or steam a letter open on Shabbat. It’s permissible to tell a non-Jew that it’s forbidden to open letters on Shabbat so that the non-Jew will understand to open it as this is not a command but only a hint. [12] Similarly, it’s permissible to benefit from the letter since the action of the non-Jew was applied to the envelope and not to the letter directly.[13]
- It’s permissible to open an envelope or a booklet that was stapled shut just for transmission by post by removing the staples. However, it’s forbidden to remove the staples from two papers that were stapled together permanently. [14] Similarly, it’s forbidden to staple an envelope closed.[15]

- ↑ Mishna Brurah 340:41 writes that ripping toilet paper in order to wipe is forbidden (Deoritta) as Kore’ah. This is also the opinion of Shemirat Shabbat KeHilchata 9:25, Or Letzion 40:6, Orchot Shabbat (vol 1, 11:21), and Shalmei Yehuda (10:9, pg 171) in name of Rav Elyashiv. The reasons that ripping toilet paper is forbidden are (1) kore'ah, and (2) makeh bpatish. Fundamentally, it is similar to the Mishna Beitzah 32b that ripping paper for roasting a fish is makeh bpatish and it seems that it isn't kore'ah. Furthermore, Rambma (Hilchot Shabbat 22) implies that it is only makeh bpatish on a rabbinic level. Why wouldn't it be considered kore'ah? (A) Bet Yosef 317:3 suggests that ripping something that isn't meant to be used for stitching it up afterwards isn't kore'ah on a Torah level. This is also the view of Ritva and Ramban Shabbat 48a and Makot 3b. Seemingly, this is also the view of Tosfot Shabbat 73b. However, Biur Halacha (340:14 s.v. vlo) rejects this opinion completely and holds that it is against the Gemara Shabbat 105b. (B) Shulchan Aruch Harav 340:17 holds that it isn't considered kore'ah if the item being ripped is one material; kore'ah is only ripping two items that were stitched or glued together. Nishmat Adam 29:2 agrees with this. However, Biur Halacha (340:13 s.v. ein) completely rejects this possibility based on Yerushalmi (Shabbat 7:2 12a). Kesot Hashulchan defends the Shulchan Aruch Harav. (C) Biur Halacha 340:13 s.v. ein holds that it isn't kore'ah if you're not trying fix both sides of the item being ripped. When ripping a paper off of a larger paper that's not being used that isn't kore'ah. Nonetheless, it should violate makeh b'patish at least on a rabbinic level.
