Dose of Halacha

Question: I often learn in the room next to the Beis Hamedrash while they are davening . Do I need to join in for Kaddish , Kedusha , or Barchu ? Answer: The Gemara (Berachos 8b) teaches that one must not walk behind a shul while the tzibbur is davening as this creates the false impression that the person is avoiding tefilla . There are several exceptions, such as where there is another shul nearby, in which case it can be assumed that he intends to daven there. This halacha is codified by Rambam (Tefilla U’birchas Kohanim 6:1) and the Shulchan Aruch (OC 90:8).

The Kesef Mishna (Tefilla 11:6) explains that entering a shul simply to relax or de-stress is not permitted; one should enter only to daven or to read from the Torah. The Talmud Yerushalmi (Shekalim 5:4) recounts that R’ Chama bar Chanina and R’ Hoshiya once walked through a shul in Lod. R’ Yitzchak Falaji (Yafeh Lelev OC 151:2) explains that talmidei chachamim may do so, as their walks are considered a form of simchas mitzva , helping to prepare the mind for Torah learning and reflection (see Shaar Hatziyon 151:9).
