After Shacharis, it is customary to put on [in addition] the tefillin that are made according to the teaching of Rabbeinu Tam,[147] but without a blessing. While wearing them one reads the Shema; some people are accustomed [and in practice this is universal usage] to proceed with the passage beginning with vayedaberi...kadeish, and to continue with v'hayah ki y'viacha (p. 85).

While wearing the tefillin of Rabbeinu Tam one should first recite the three paragraphs of Shema (p. 46), and then the above-mentioned passage.[148] When wearing the tefillin of Rabbeinu Tam, Shimusha Rabba and Raavad one does not repeat the words ani Hashem Elokeichem, but one does add the word emes.[149]

It is fitting and proper to put on the tefillin of Rabbeinu Tam immediately after Shacharis, for then they are included in the blessing which has been said over the tefillin of Rashi (since the intervening prayer is an incomparably lesser interruption than are one's subsequent mundane pursuits). This view may be supported by the practice of saying Tefillas HaDerech (p. 86) after Shacharis (see HaYom Yom, p. 72).[150] If it is impossible to put on the tefillin of Rabbeinu Tam immediately, one can do so up to sunset.[151]

   

Notes:

147. (Back to text) [The above is the wording that appears in the Alter Rebbe's Siddur, at the appropriate point in Shacharis. However:] Under the heading of Hilchos Tefillin in the Siddur, the Alter Rebbe writes: "Every man whose heart has been touched by the fear of G-d should put on the tefillin of Rabbeinu Tam." The reason for the repetition of the subject, and the reason for the difference in wording, warrants further study.

     "It is also somewhat puzzling why the custom has spread - and this includes Anash - to begin putting on the tefillin of Rabbeinu Tam quite some time after bar-mitzvah, generally after marriage. This has been commented on by R. Avraham Chayim Naeh in Piskei HaSiddur. Likewise, the author of Os Chayim (34:10) seeks a satisfactory explanation for this delay, though his own view is that one should begin at bar-mitzvah." (Note of the Rebbe Shlita in Likkutei Sichos, Vol. II, p. 507; see there at length.)

     [Since the above lines were written by the Rebbe Shlita in the course of a footnote to the published version of a sichah delivered in 1950, the universal custom among Chabad-Lubavitch chassidim has become to begin putting on the tefillin of Rabbeinu Tam at the same time as the tefillin of Rashi. (See Sefer HaSichos 5749, Vol. II, p. 632, and footnote there.)]
