* The Mishnah ([[Shabbat]] 113a) writes that one may fold clothing on [[Shabbat]]. Rashi (s.v. Afilu) limits this to where one is folding the clothes in order to wear them again that day. Tosfot (s.v. Mekaplin) infers that it would be forbidden to fold clothing that would be needed only after [[Shabbat]]. This is codified by the Rif 41b, Rambam 22:22, Rosh 15:2, Tur, and S”A 302:3. From this and other halachot, the poskim explain that in general there is a Rabbinic prohibition of preparing on [[Shabbat]] for the weekday (See Orchot [[Shabbat]] vol 2, p. 400).

* In explaining the concept of Hachana, the Rambam ([[Shabbat]] 23:7) writes that cleaning dishes that one does not need to use on [[Shabbat]] is considered Metaken, whereas the Raavad argues that it is prohibited because it involves exerting effort for something that is needed during the week. Nonetheless, the [[Maggid]] Mishneh and Migdal Oz explain that the Rambam agrees with the Raavad and that his intention was that it is an issue of fixing the dishes for after [[Shabbat]]. Tzitz Eliezer 14:37 writes that this also is the opinion of Rashi.</ref> It is permitted to prepare on [[Shabbat]] for later on [[Shabbat]], and even for [[Tosefet Shabbat]] (the extension of [[Shabbat]]).<ref> Sh”t Minchat Shlomo 2:36:10 writes that there is no prohibition of preparing from [[Shabbat]] to [[Tosefet Shabbat]] because even [[Tosefet Shabbat]] is called “Yom HaShabbat HaGadol HaZeh” in Birkat Hamazon. Orchot [[Shabbat]] (vol 2, p. 408) agrees. </ref>

* Shemirat [[Shabbat]] KeHilchata (chap 28, note 206 and in new editions 220) quotes Rav Shlomo Zalman who was in doubt regarding whether it’s considered Hachana to study secular subjects not for the knowledge but only to do well on a test during the week. 39 Melachos (vol 4, pg 982) rules that it’s forbidden because of Hachana.

* Yalkut Yosef ([[Shabbat]], vol 2, pg 216) rules that one may only learn Torah on [[Shabbat]] and the only exception is a medical student who has a test after [[Shabbat]] and is pressured for time to study medicine (except for the study of surgery) on [[Shabbat]]. Though in that one case where it is permissible to learn secular studies on [[Shabbat]] it is only permitted with regards to Hachana.

* Aruch HaShulchan 323:7 writes that if one has sufficient dishes or cups for the rest of [[Shabbat]], it is improper to clean anything. [[Tosfet Shabbat]] 323:8, Kaf HaChaim 323:39, Shevet HaLevi 5:39 and 6:42, Bear Moshe 6:82, Yalkut Yosef (vol 4, p. 21), and Menuchat Ahava (vol 1, 11:4) agree. Mishneh Halachot 3:40 and 6:80, however, permits [[cleaning the dishes]] for a [[Shabbat]] meal even if one has other dishes, because in essence one is cleaning for the purpose of [[Shabbat]] and not for the weekday. Rav Moshe Feinstein (cited in Kol Torah vol 54 p. 18), Rav Nissim Karelitz (cited by Orchot [[Shabbat]] p. 404), and Brit Olam (p. 66) agree.

* Bnei Tzion 323:9 brings a proof to the Aruch HaShulchan from a halacha in regards to folding clothes. The Mishna (113a) writes that one may fold clothes on [[Shabbat]], but the Gemara limits this to a case where one doesn’t have any other clothes. The Raavan (Chap 15) explains that if one were to have other clothes, folding one’s clothes would be considered [[preparing for after Shabbat]]. Similarly, the Biur HaGra also explains that this is the source for Rashi’s claim that one may only fold clothes if one needs to wear them again on [[Shabbat]]. The Ri (Tosfot 113a s.v. Yesh) has a doubt whether a person who has other clothes which aren’t as nice as the ones he wants to fold is allowed to fold his clothes or not. The Mishna Brurah 302:17 and Kaf HaChaim 302:29 rule that it is forbidden to fold clothes even if the other clothes aren’t as nice. Nonetheless in Shaar HaTziyun 302:17 he adds that the clothes which one wouldn’t wear on [[Shabbat]] aren’t considered a valid alternative, which would prevent one from folding one’s clothes. </ref>
