A garment to which the Torah obligates a person to attach tzitzit¹ [must meet the following requirements]: a) it must have four² - or more than four³ - corners; b) it must be large enough to cover both the head and the majority of the body of a child⁴ 41a adds that the garment must be large enough for an adult to use it occasionally. This requirement is particularly significant regarding a tallit katan. Note the Mishnah Berurah 16:4, which requires that a tallit katan be at least 0.75 of a cubit long and 0.75 of a cubit wide on each side, without including the area of the hole where one's head is inserted. Preferably, the tallit katan should be a cubit by a cubit on each side. who is able to walk on his own in the marketplace without having someone else accompany him and watch⁵ (Orach Chayim 16) defines this as referring to a child who is at least nine years old. him; c) it must be made of either wool or linen alone.⁶

footnotes: ¹ With this expression, the Rambam could be alluding to the concept that a person is not obligated to wear tzitzit. Should a person desire to wear a garment of the type that requires tzitzit, then he has the opportunity to fulfill the mitzvah. See Halachot 10-11. ² Deuteronomy 22:12 states: "Make braids on the four corners of your garments." As explained in Halachah 3, this excludes a garment with fewer than four corners. ³ corners; - See Halachah 3. ⁴ Menachot ⁵ The Tur ⁶ as explained in the following halachah.

In contrast, a garment made of other fabrics¹ - for example, clothes of silk, cotton, camels' wool, hares' wool, goats' wool, and the like² (Orach Chayim 9:1). The Ashkenazic authorities, however (see the Ramah), disagree and maintain that all four-cornered garments require tzitzit regardless of the fabric they are made of. This difference of opinion results from the interpretation of a debate between Amoraim (Menachot 39b). Because of this difference of opinion, the Shulchan Aruch (Orach Chayim 9:6) suggests that everyone wear a tallit of wool, so that he will fulfill the mitzvah as required by the Torah according to all opinions. Shulchan Aruch HaRav 9:4 and the Mishnah Berurah 9:5 suggest that a God-fearing person should have both his tallit gadol and his tallit katan made of wool. See also the commentary on Halachah 5. - are required to have tzitzit only because of Rabbinic decree, in order to show regard for the mitzvah of tzitzit.³ [These garments require tzitzit only] when they are four-cornered⁴ - or have more than four corners - and are of the measure mentioned above. [The motivating principle for this law]⁵, ibid. is that all the garments mentioned in the Torah without any further explanation⁶ refer to those made of either wool or linen alone.⁷, Hilchot Kilayim 10:1) and the laws of tzara'at (leprosy, Hilchot Tumat Tzara'at 13:1), the Torah mentions garments of wool and linen, we can assume that any place in the Torah which mentions the word "garment" is referring to one made from wool or linen unless another fabric is explicitly mentioned.

This concludes the quotation from the Talmud. ¹² Since the reason tzitzit are placed on a five-cornered garment is that it possesses four corners ¹³ Indeed, if one attaches tzitzit to more than four corners of the garment, one transgresses the prohibition against adding to a Torah commandment (Magen Avraham ¹⁴ for, in this way, the tzitzit will be more noticeable (Shulchan Aruch HaRav ¹⁵ There are other opinions, which maintain that a garment with more than four corners does not require tzitzit. In consideration of these opinions, it is preferable not to wear such garments at all (Magen Avraham

If a garment is made of cloth¹ and its corners of leather, it requires tzitzit.² 10:8; Mishnah Berurah 10:10). If the garment is of leather and its corners are of cloth,³ it does not require tzitzit. The determining factor is the makeup of the garment itself.⁴ A garment belonging to two partners requires [tzitzit], as [implied by Numbers 15:38]: "On the corners of their garments."⁵ The term "your garments"⁶ [(Deuteronomy 22:12 , which is interpreted as an exclusion,] excludes only a borrowed garment, since a borrowed garment does not require tzitzit for thirty days.⁷ 14:3-4). Afterwards, it does require them.⁸, which explain that, even after thirty days, the Torah does not require a person to attach tzitzit to a garment which is not his own. The Sages, however, imposed this obligation because the garment appears to be his.

As long as the majority of the garment is cloth, it requires tzitzit (Shulchan Aruch HaRav ³ In this case as well, as long as the majority of the garment is leather ⁴ This is derived from the conclusion of the verse from Deuteronomy, "with which you cover yourself." A person covers himself with the major portion of the garment (Rabbenu Manoach). ⁵ Here, the usage of a plural term implies an inclusion of garments which belong to many owners.In contrast, ⁶ In this verse, the singular form of the word "your" is used. ⁷ Nevertheless, one is allowed to attach tzitzit to the garment if one chooses. Furthermore, one is allowed to borrow a colleague's tallit and recite a blessing over it - even without his knowledge (Shulchan Aruch, Orach Chayim ⁸ Note the Hagahot Maimoniot

For a garment of wool, the white strands should be made of wool.¹ For a garment of linen, the white strands should be made of linen.² For garments of other [fabrics],³ 39b.) According to the Rambam, who maintains that the requirement of tzitzit on these garments is Rabbinic in origin, we must assume that these concepts were part of the Rabbinic ordinance requiring tzitzit for these garments (Kessef Mishneh). the white strands should be made from the same fabric as the garment itself.⁴ For example, silk strands should be used for a silk garment, strands of goats' wool should be used for garments of goats' wool.⁵ 9:4). If one desired to make white strands of wool or linen⁶ 9:2) states that at present it is customary not to make linen tzitzit at all. for [garments of] any type [of fabric], one may,⁷, ibid., derives this concept from the fact that Deuteronomy 22:12 mentions the mitzvah to attach tzitzit to our garments directly after the mention of the prohibition of making garments of wool and linen. Our Sages explain, that although mixtures of wool and linen are forbidden in general, such a mixture is required in tzitzit. (See the following two halachot.) Therefore, whenever tzitzit are made, either of these two fabrics may be used. because [strands of] wool and linen can fulfill the obligation [of tzitzit] for garments made of their own fabric or for garments made of other fabrics.⁸ can be used to fulfill the obligation of tzitzit for garments made from other fabrics. Shulchan Aruch HaRav 9:4 suggests considering this opinion. In contrast, [strands made] from other fabrics can fulfill the obligation [of tzitzit] only for garments made of their own fabric.⁹ 9:5 and the Mishnah Berurah 9:10,13 which discuss a situation where the garment is woven from both wool and another fabric.

footnotes: ¹ alone. ² alone. Note the explanation in the following halachah. ³ As mentioned in the commentary on Halachah 2, there is a difference of opinion among the Rabbis whether garments made from fabrics other than wool or linen require tzitzit or not. According to the opinions which maintain that they do, the concepts that follow are derived from the exegesis of a Biblical verse. (See Menachot ⁴ The authorities who consider the obligation to attach tzitzit to such garments as stemming from the Torah explain that, in the commandment to attach tzitzit, the Torah mentions the word "corner" an extra time, to teach that the tzitzit should be made of the same fabric as the corners. ⁵ If one chooses to make tzitzit from these fabrics, one should use them for all four tzitzit. It is questionable whether it is acceptable to make some of the tzitzit of a specific garment from wool and others from the fabric of which the garment is made (Shulchan Aruch, Orach Chayim ⁶ The Ramah (Orach Chayim ⁷ Menachot ⁸ Rabbi Meir of Rothenberg maintains, however, that wool and linen strands alone are not sufficient, and only a combination of wool and linen including strands of techelet ⁹ Note Shulchan Aruch HaRav

Thus, one can conclude that when attaching tzitzit to a linen garment, it is forbidden to make the white strands of wool even though one includes a woolen strand oftechelet. Though the prohibition against sha'atnez is lifted for this garment, it is lifted only when there is no alternative but to do so (Kessef Mishneh). - even though we are speaking only of the white strands without techelet? One might think that it should be permitted, because sha'atnez², Chapter 10.) is permitted to be used for tzitzit, as evident from the fact that techelet is made using woolen strands,³ and yet it should be placed on a linen garment.⁴ Nevertheless, this⁵ is not done. Why? Because it is possible to make the white strands from the same fabric as [the garment].⁶ Whenever [a conflict exists] between the observance of a positive commandment and the adherence to a negative commandment, [the following rules apply]:⁷ 1:9. If it is possible to observe both of them,⁸ one should. If not, the observance of the positive commandment supersedes the negative commandment.⁹ (Iggeret HaTeshuvah, Chapter 1) explains the rationale for this principle. Man's purpose in this world is to spread Godly light through the observance of mitzvot. Accordingly, the observance of these mitzvot is always given preference when there is such a conflict. It must be emphasized that one must fulfill the mitzvah at the time one is violating the transgression. It is forbidden, however, in order to break a commandment to later perform a mitzvah. In the present instance, however, it is possible to observe both of them.¹⁰

footnotes: ¹ even though we are speaking only of the white strands without techelet? - It appears that the Rambam is asking about attaching tzitzit that have only white strands, without attaching techelet ² a mixture of wool and linen which is forbidden. (See Deuteronomy 22:11 and Hilchot Kilayim ³ Chapter 2, Halachot 1- 2. ⁴ according to Torah law. See, however, the following halachah. ⁵ Using linen strands for a woolen garment or vice versa ⁶ Woolen strands for a woolen garment, linen strands for a linen garment, and thus skirt the prohibition entirely. ⁷ The following are general rules which apply, not only regarding tzitzit, but in other circumstances as well: for example, Hilchot Milah ⁸ by fulfilling the positive commandment without breaking the prohibition ⁹ Rav Nissim Gaon explains that although the violation of a negative commandment receives a more severe punishment than the failure to observe a positive commandment, when God originally gave the negative commandments, He prescribed that they do not apply when adherence to them causes the performance of a positive commandment to be nullified.The Tanya ¹⁰ as explained above.144

Techelet should not be attached to a linen garment.¹ was available. Rather, one should [make the tzitzit] from white threads of linen alone.² This is not because [the prohibition against] sha'atnez supersedes [the mitzvah of] tzitzit, but rather it is a Rabbinical decree³ [imposed] lest one wear the garment at night,⁴ 40b) exactly. The Talmud states "lest one wear a garment of the night." The Rambam's change of phraseology teaches two concepts. First, that not only a garment which is generally worn at night, but even one which is worn primarily during the day, should not have techelet attached to it, lest one wear it during the night. This also sheds light on a more involved issue. There is a difference of opinion among the Rabbis if the exclusion of wearing tzitzit at night applies to all tzitzit, or if it applies only to garments which are worn primarily at night. According to the latter opinion, garments worn primarily at night do not require tzitzit, even when worn during the day. In contrast, a garment which is worn primarily during the day requires tzitzit, even during the night and one does not transgress the prohibition against sha'atnez when wearing it at that time. By altering the terminology used by the Talmud, the Rambam indicates his acceptance of the first perspective. Rabbenu Asher is the primary exponent of the second position. The Shulchan Aruch (Orach Chayim 18:1) mentions both views without reaching a conclusion. when one is not required to wear tzitzit, and thus violate a negative commandment when the performance of a positive commandment is not involved.⁵ 10:32, which mentions a similar concept regarding the priestly garments. The sash worn by the priests was made from sha'atnez. Therefore, the priests were allowed to wear it only when they were actually involved in the Temple service. Wearing it at other times constitutes a transgression, and not a mitzvah. Significantly, Rabbenu Tam differs with the Rambam and allows the sash and tzitzit to be worn even during the times when doing so does not fulfill a mitzvah. [This is because] the obligation to wear tzitzit applies during the day, but not at night [as can be inferred from Numbers 15:39]: "And you shall see them."⁶ 8:13, which states that this verse also implies that one should wear tzitzit in a manner in which the strands can be seen. [The mitzvah applies only] during a time when one can see.⁷ and Rabbi Akiva Eiger (Orach Chayim 18), who mention opinions that maintain that the mitzvah is not limited by the times of day and night, but rather by situations when one can see the tzitzit. During a daytime eclipse, one would not be obligated. [Nevertheless,] a blind man is obligated to wear tzitzit. Even though he does not see them, others see him [wearing them].⁸ 17:1).

footnotes: ¹ This decree was imposed even when techelet ² even though by doing so, one does not fulfill the mitzvah of tzitzit to the fullest degree. ³ The Rabbis have the power to ordain that a person bypass the performance of a Torah commandment. Surely this applies in the present instance, when the mitzvah of tzitzit is not nullified entirely. ⁴ Significantly, the Rambam does not quote his apparent source (Menachot ⁵ See Hilchot Kilayim ⁶ Note the Magen Avraham ⁷ i.e., the daytime hours. Note the Chatam Sofer ⁸ There is no question concerning a blind man's obligation. He is required to wear tzitzit and may recite a blessing beforehand (Mishnah Berurah

A person is permitted to wear tzitzit at night,¹ 21:15 quotes the Ari zal, as advising one to sleep in a tallit katan at night. both during the weekdays². Based on the previous halachah, however, most authorities do not accept this opinion. and on the Sabbath,³ 19:20). even though this is not the time when the mitzvah should be fulfilled, provided he does not recite a blessing.⁴ is put on during the night - e.g., before the Selichot prayers - a blessing should not be recited (Ramah, Orach Chayim 18:3). When should the blessing over tzitzit be recited in the morning?⁵ at night or not. Nevertheless, because of Rabbenu Asher's opinion mentioned in the previous halachah, if someone slept in his tallit katan, he should not recite a blessing upon it in the morning. Instead, it is preferable that he recite the blessing over his tallit gadol with the intention of including the tallit katan (Mishneh Berurah 8:24). When [the sun has risen so] that one can differentiate between the strands of techelet and those which are white.⁶ 18:3), who allows the blessing to be recited from dawn onwards. Which blessing should be recited upon it? "Blessed are you, God, our Lord, King of the universe, who has sanctified us with His commandments and commanded us to wrap ourselves with tzitzit."⁷. For a tallit katan, most authorities suggest concluding al mitzvat tzitzit, "concerning the mitzvah of tzitzit." Whenever a person wraps himself in tzitzit during the day, he should recite the blessing before doing so.⁸ (Orach Chayim 8:14) and the Ramah, whether a person who removes his tallit with the intention of putting it on again in the near future is obligated to recite a blessing or not. No blessing should be recited on the tzitzit when making them,⁹ 11:9, which states that one should recite the blessing, shehecheyanu, when one acquires or makes tzitzit. (See Shulchan Aruch, Orach Chayim 22:1.) because¹⁰ the ultimate purpose of the mitzvah is that one should wrap oneself in [a tallit].¹¹ 5:7; Hilchot Berachot 11:8.

Therefore, one might think that it is forbidden to wear a garment with tzitzit at night, for it would be considered as if one is carrying them. The Rambam is teaching us that the tzitzit are not considered to be a burden, but rather an adornment of the garment to which they are attached (Hilchot Shabbat ⁴ Therefore, when a tallit ⁵ According to the Rambam, this question applies whether one wears his tallit ⁶ This time is slightly more than midway between dawn (עלות השחר) and sunrise (הנץ החמה).Note the Ramah (Orach Chayim ⁷ This is the blessing recited over the tallit gadol ⁸ Note the difference of opinion between the Shulchan Aruch ⁹ Note Hilchot Berachot ¹⁰ making the tzitzit or even attaching them to the garment is only a preparatory act ¹¹ See Hilchot Mezuzah

It is permissible to enter a lavatory or a bathhouse [wearing] tzitzit.¹ 21:3 and the Mishnah Berurah 21:14 state that it is improper to enter a lavatory wearing a tallit gadol. Since this garment is worn exclusively at the times of prayer, it is not fitting to wear it in a lavatory. If one of the strands of white or techelet becomes torn, it may be discarded in a garbage dump,² 10:3-4.) The Ramah (Orach Chayim 21:1) differs and maintains that even after tzitzit have been removed from a garment, they should not be treated with disrespect. because tzitzit is a mitzvah which does not confer sanctity on the article itself.³ It is forbidden to sell a garment with tzitzit to a gentile until he removes the tzitzit, not because the garment possesses a measure of holiness,⁴ 5:11.) but because we are concerned that he will dress in it, and [unknowingly,] a Jew will accompany him, thinking that he is a fellow Jew, and the gentile may kill him.⁵ 12:7, which forbids traveling together with a gentile. Women,⁶ 12:3.) Since tzitzit are worn only during the day, women are not obligated to wear them. servants,⁷ 1:2 and Hilchot Issurei Bi'ah 12:11, 14:9.) A Jew sold as a slave is required to fulfill all the mitzvot. and minors⁸ are not required by the Torah to wear tzitzit.⁹ (Vol. 17) notes that the Rambam's choice of phraseology appears to indicate that the requirement to become trained in the performance of mitzvot obligates the child himself. Generally, it is understood that the obligation is on the child's parents, who are required to train him in Torah observance. The contention that the obligation is on the child himself is supported by Hilchot Berachot 5:15-16, which states that an adult who has eaten only a small meal can fulfill his obligation to recite the grace by answering "Amen" to the blessings recited by a child who has reached the age of education. This ruling is based on the rationale that both the child and the adult share the same degree of obligation, a Rabbinical decree. This appears to indicate that the Sages placed the obligation to recite grace on the child himself. It is, however, a Rabbinical obligation for every child who knows how to dress himself¹⁰ 17:3) interprets this to mean, "knows how to wrap himself in tzitzit in the ritual manner." to wear tzitzit in order to educate him to fulfill mitzvot.¹¹ from the time he is toilet trained. In other communities, a child begins to wear tzitzit from the age of 6. Women and servants who wish to wrap themselves in tzitzit may do so¹² 17:1), however, advises against women wearing tzitzit, explaining that doing so would be a sign of conceit. without reciting a blessing. Similarly, regarding the other positive commandments which women are not required to fulfill, if they desire to fulfill them without reciting a blessing, they should not be prevented from doing so.¹³ 17:1 explains that the fact that, as our Sages relate, women are given some measure of reward for the fulfillment of these commandments indicates that the commandment applies - albeit not completely - to them as well. A tumtum¹⁴ has its roots in the word atum, which means "a solid block." It refers to a person whose genitalia are covered by skin, so that it is impossible to determine whether he is male or female. (See also Hilchot Avodat Kochavim 12:4, Hilchot Ishut 2:25.) Should a tumtum undergo an operation and it be revealed that he is either male or female, he is bound by the laws which apply to that gender. and an androgynous¹⁵ is a combination of the Greek words meaning "man" and "woman." It refers to a person who possesses the sexual organs of both genders. (See also Hilchot Ishut 2:24.) are obligated in all positive commandments because of the doubt [about their status].¹⁶, we are uncertain what is his true gender. With regard to an androgynous, however, the question revolves around the Sages' failure to define his status. Therefore, they fulfill [all these positive commandments] - lest they be considered men. without reciting a blessing. - lest they be considered women. Needless to say, according to Ashkenazic practice, they would be required to recite blessings as well. Therefore, they fulfill [all these positive commandments] without reciting a blessing.

What is the nature of the obligation of the commandment of tzitzit? Every person who is obligated to fulfill this mitzvah,¹ if he wears a garment requiring tzitzit,² should attach tzitzit to it and then wear it.³ If he wears it without attaching tzitzit to it, he has negated [this] positive commandment. There is, however, no obligation to attach tzitzit to a garment which requires tzitzit, as long as it remains folded in its place, without a person wearing it.⁴ It is not that a garment requires [tzitzit].⁵ 42b. There are Sages who maintain that tzitzit is an obligation that depends on the garment - i.e., the mitzvah is completed by placing tzitzit on every garment which requires them. The other opinion states that tzitzit are an obligation incumbent on a person, that a person is required to attach tzitzit to his garments. The Rambam rephrases the latter opinion as follows: Rather, the requirement is incumbent on the person [wearing] the garment.⁶, at the conclusion of the listing of the positive commandments, he lists tzitzit (together with tefillin) as one of the positive commandments whose observance we must pursue. Here, his choice of phraseology indicates that, although the mitzvah is incumbent on the person, it does relate to the garment. Only when a person wears a garment which requires tzitzit is he obligated to fulfill the mitzvah.

footnotes: ¹ i.e., adult males, as explained in the previous halachah ² See Halachot 1-4. ³ if he desires to do so. ⁴ 13The Rambam wants to emphasize that ⁵ The Rambam's statements in this halachah revolve around a difference of opinion of our Sages, Menachot ⁶ With this choice of phraseology, he desires to indicate that - in contrast to other mitzvot (e.g., tefillin) - there is no obligation from the Torah to wear tzitzit every day. Only when a person desires to wear a garment that requires tzitzit is he obligated to fulfill the mitzvah.This conception represents a change of position for the Rambam. Rav Yitzchak Alfasi, whose decisions the Rambam frequently followed, maintains that each person is obligated to wear tzitzit, apparently indicating that tzitzit, like tefillin, are an obligation which a person is required to fulfill.The Rambam apparently held this view himself at one time. Therefore, in Sefer HaMitzvot

Even though a person is not obligated to purchase a tallit and wrap himself in it so that he must attach tzitzit to it,¹ it is not proper for a person to release himself from this commandment. Instead, he should always try to be wrapped in a garment which requires tzitzit so that he will fulfill this mitzvah.², a garment of the size and cut appropriate for "wrapping oneself." Significantly, throughout these halachot, he has used that term and never makes any reference to a tallit katan, the smaller garment which is colloquially called "tzitzit" today. In Talmudic times, draping oneself with a garment that resembled our tallitot gedolot was common, but in different lands and different eras, the style of dress changed and, except for sages who would spend their day involved in study, it was rare that a person would wear a tallit gadol throughout the day. Accordingly, the people took to wearing the smaller tallit katan, which could be accommodated to other styles of dress more easily. There is no explicit mention of a tallit katan in the Talmud, although a story related in Menachot 44a appears to indicate that such garments were worn in that era as well. The writings of the early Ashkenazic and later Sephardic rabbis of the Middle Ages mention the wearing of a tallit katan as an accepted practice. In particular, care should be taken regarding this matter during prayer.³ It is very shameful for a Torah scholar to pray without being wrapped [in a tallit].⁴ 17b, which relates that when God revealed the thirteen qualities of mercy to Moses, "He wrapped Himself [in a tallit] like a leader of prayer and taught him the order of prayer."

footnotes: ¹ as explained in the previous halachah. ² because of the importance of this mitzvah, as mentioned in the following halachah.The Rambam mentions being "wrapped in a garment requiring tzitzit," an expression which appears to refer to a tallit gadol ³ The Rambam does not specify the morning service. Perhaps he refers to the afternoon service as well. ⁴ See Rosh HaShanah

A person should always be careful regarding the mitzvah of tzitzit, because the Torah considered it equal to all the mitzvot and considered them all as dependent on it, as [implied by Numbers 15:39]: "And you shall see them and remember all the mitzvot of God."
