Responsa for Shabbat 123:16

Regarding those men who wear rings on their hands, and walk out wearing them in the public domain on Shabbat. They rely on the Mishnah (Shabbat 6:10) "One may go out with a locust’s egg, a fox’s tooth, and a nail from the cross of a convict for purposes of healing." They say that gold, too, is carried for the purpose of healing. I asked [in my dream] if their reasoning makes any sense. If it doesn't, they are liable for a transgression, as in the ruling of the Mishnah¹Mishnah Shabbat 6:1. Rashi and Tosafot disagree on the Talmud's reinterpretation of the mishnaic text (Shabbat 62a:9). The reading proposed here fits Rashi on Shabbat 62a:9, as well as Rif Shabbat 28b, whereby wearing a ring with no signet is considered carrying for a man, and he is liable to bring a sin-offering.
