Chapter Fourteen Al HaShulchan page 38-39
1. According to some authorities most people nowadays are particular that others should not wear their zizit or tefillin, and therefore one should not take from the Shamash (synagogue attendant) zizit or tefillin belonging to others unless the Shamash is certain that the owner is not particular. (Ben Ish Chai Lech Lecha 6). If someone received a tallit from the Shamash and recited the blessing over it but, before he was able to wrap it around himself, the Shamash took it away from him saying that the owner had arrived and required it for himself, and then he gives him another tallit, he does not recite another blessing, as there are different opinions among the authorities whether this is necessary and we apply the rule that in the case of doubt whether to recite a blessing we are lenient and do not repeat the blessing. (Mayan Ganim Part 2:6)

We would like to dedicate this learning for the speedy and complete recovery of several people, including Gittel bas Yehudis, Mendel ben Florence, Chasha Baila bas Rasha, our friends' 5-year-old son, Joseph Benjamin, son of Ireneusz Khrystof, diagnosed in April with ALL leukemia, and a longtime friend of the family, Franco, son of Joseph, who is B"H recovering from thyroid surgery. Please have them in mind when studying. If you would like updates on their progress, please let me know so I can tell you when I find out from either or both.
