The Gemara in Masechet Moed Katan (15a) states: “What is the law regarding one under niddui and tefillin?” The question remains unresolved. The Beit Yosef (Orach Chaim, siman 38) cites the Baal HaIttur (Hilchot Tefillin, vol. 7, section 1, p. 74), who rules that one under niddui is forbidden to wear tefillin. Likewise, the Shulchan Aruch (ibid., at the end, סעיף 13) rules that one under niddui is forbidden to wear tefillin. However, the Shach (Yoreh De’ah, siman 334, se’if katan 12) writes that the consensus of most poskim is that one under niddui is obligated to wear tefillin. In his commentary Olat Tamid on Orach Chaim, he leaves unresolved why the Shulchan Aruch in Yoreh De’ah did not state that one under niddui is forbidden to wear tefillin.
The Tur, in Yoreh De’ah there, cites an opinion that we rule stringently in this matter and that one under niddui does not wear tefillin, since this doubt was not resolved in the Gemara. He writes that the Rif and the Rosh rule leniently, that he does wear tefillin. The Gra writes in Orach Chaim there that the Raavad likewise rules this way, and that this also appears to be the view of the Shulchan Aruch in Yoreh De’ah, as the Shach ruled there. It appears from his words that he wears tefillin even with a blessing, and the Mishnah Berurah there likewise inferred this from his words. However, the Pri Megadim writes that he should wear them without a blessing, and the Kaf HaChaim writes that this is the primary halachah: he should wear tefillin without a blessing. This is also implied by the words of the Shulchan Aruch in Yoreh De’ah, that one under niddui is obligated to wear tefillin, as stated above. See the extensive discussion of this matter in the sefer Halachah Berurah there.
