Dose of Halacha

Question: After doing hagbah , the gabbai told me that I should have removed the tefillin straps from my hand. Is this necessary? Answer: The Gemara (Arachin 3b) teaches that the kohanim did not wear the tefillin shel yad while performing the avoda, as this would constitute a chatzitza, a separation between the bigdei kehuna and their skin. Elsewhere, the Gemara (Zevachim 19a) teaches that kohanim , leviyim and yisraelim were exempt from wearing tefillin during the avoda . Rashi explains that this follows the rule of osek bemitzva, patur min hamitzva, one who is engaged in performing a mitzva is exempt from another. Rambam (Klei Hamikdash 10:6) adds that the kohanim could, if they wished, wear the tefillin shel rosh during the avoda . Sefer Haeshkol (Tefillin 30) records the practice of removing the tefillin straps from one’s hand during duchening , reflecting the precedent of the kohanim during the avoda in the Beis Hamikdash. However, the Kaf Hachaim (OC 128:8...

Question: We bought tefillin from Eretz Yisrael for our son who is becoming bar-mitzva . May we go to our local sofer at nighttime to try them on and adjust them? Answer: The Gemara (Eruvin 96a; Menachos 36a) teaches that one should not put on tefillin at nighttime. The Shulchan Aruch (OC 30:2) explains that this is due to the concern that one may inadvertently fall asleep while wearing them. The Kaf Hachaim (OC 30:7) adds that the Arizal was particularly careful to remove them at night for kabbalistic reasons. R’ Shamai Gross (Shevet Hakehasi 6:15) permits trying on tefillin at night for practice. He cites the Shulchan Aruch (OC 30:3), which allows wearing tefillin at night in certain travel situations where there is no concern of dozing off. Accordingly, wearing them briefly at night when not for the mitzva itself poses no difficulty, and even according to the Kaf Hachaim, trying them on at night is acceptable. R’ Moshe Stern in Baer Moshe (8:47:1) emphasises that ther...

Question: I woke up late and realised that I had left my tefillin in school. I davened Shacharis without wearing tefillin before sof zeman tefilla . Should I put on my tefillin at the first opportunity, or wait to wear them during mincha ? Do I need to repeat Shema ? Answer: The Gemara (Berachos 14b) teaches that a person who recites the Shema in the morning without wearing tefillin is considered as though he is giving false testimony about himself. Tosafos explains that this is because one is reciting the words of the mitzva to wear tefillin while not fulfilling it in practice. Accordingly, Rambam (Tefillin 4:26) and the Shulchan Aruch (OC 25:4) rule that one should wear tefillin while reciting the Shema . The Mishna Berura (25:14) adds that this applies only when one deliberately chooses not to wear tefillin . However, someone who does not have tefillin available, or is unable to wear them due to extreme circumstances, has not transgressed and should nevertheless recite...
