אבל ביום ראשון אסור להניח תפילין. ובו ב' סעיפים:אבל אסור להניח תפילין ביום ראשון ואחר שהנץ החמה ביום ב' מותר להניחם:
A mourner is forbidden to don Tefillin1 Glos. M.K. 15a, derived from, ‘Bind thy headtire (Tefillin) upon thee’ (Ez. XXIV, 17-23. Targum a.l.) whence it follows that for every one else this is forbidden. Cf. ibid. 21a. on the first day;2 dictum of R. Joshua in M.K. 21a (cf. also Sem(H). VI, 3; Y.Ber. III, 1(5d); Y.M.K. III, 5(82b); Gen. R. § 7; Suk. 25b), where it is stated that the exemption from Tefillin is applicable only to the first day, since of that day it is said, ‘And the end thereof as a bitter day’ (Amos VIII, 10). and after the sun rises on the second day, he is permitted3Tur on the authority of Asheri. Thus also T.H. to put them on.4If the mourner was unaware of this ruling, he must remove the Tefillin as soon as it is brought to his attention. However, if he became aware of this close to the time for the recital of the Shema, he should remove the Tefillin after he completes the reading of the Shema. This ruling (viz., not to don Tefillin on the first day) applies even if the burial does not take place on the same day as death. One who also puts on Tefillin prescribed by R.Tam (v. O.Ḥ. § 32), should not wear them during the seven days of mourning. One who receives near tidings should not don the Tefillin on the day the death report is received. One who buries his dead on a Festival day, in which case the law is that he observes mourning rites after the Festival, or one who receives a death report on the Festival, should don the Tefillin on the first day following the Festival — Later Authorites. On this ruling cf. also O.Ḥ. § 38, 5.
