סימן פד סעיף ה
הַחִגֵּר, וְכֵן הַחוֹלֶה שֶׁעָמַד מֵחָלְיוֹ, וְכֵן זָקֵן מֻפְלָג, שֶׁאִי אֶפְשָׁר לוֹ לֵילֵךְ בְּלֹא מַקֵּל, מֻתָּר לוֹ לֵילֵךְ בְּמַקֵּל בְּיָדוֹ. אֲבָל אִם אֶפְשָׁר לוֹ לֵילֵךְ בְּלֹא מַקֵּל, וּבְתוֹךְ בֵּיתוֹ הוֹלֵךְ בְּלֹא מַקֵּל, אֶלָּא כְּשֶׁהוֹלֵךְ לַחוּץ נוֹטֵל אוֹתוֹ לְהַחְזִיק בּוֹ, אָסוּר. וְכֵן הַסּוּמָא אָסוּר לָצֵאת בְּמַקֵּל בְּעִיר שֶׁאֵינָהּ מְתֻקֶּנֶת בְּעֵרוּבִין. וּמִי שֶׁאֵינוֹ צָרִיךְ כְּלָל לַמַקֵּל, אָסוּר לוֹ לָצֵאת בּוֹ אֲפִלּוּ בְּמָקוֹם שֶׁיֵּשׁ עֵרוּבִין, מִשּׁוּם זִילוּתָא דְּשַׁבָּת.
A person who is lame, or a sick person, just recovering from his illness, or a very old person, who finds it impossible to walk without a cane, is permitted to walk with a cane in his hand. But if he can walk without a cane, and he walks without one in his house, except that when he walks outside he uses it for support, he is forbidden to do so.14De’oraisa. For it is a burden, since it is not absolutely necessary for his walking. [Biur Halachah 301: 17—Ohr Zarua, Rabbeinu Yerucham] A blind person is forbidden15Some say that this is only if the blind man knows his way, but if he needs his cane in order not to trip on stumbling blocks etc., he is likened to the lame and may use his cane. [Quoted in Meiri, Maseches Beitzah 25b] to go out with a cane in a city in which there is no eiruv. A person who needs no cane at all16If it is needed as a symbol of prestige, a highly respected person may carry it within the confines of an eiruv. [Magein Avraham 301: 27] is forbidden to go out with one even in a town where there is an eiruv, because it shows disregard of the Shabbos.17It is uvda dechol, meaning, a weekday activity. Such activity is prohibited Rabbinically. See Radvaz, Tiferes Yisrael (Shabbos 6: 8). Also see Nodah Biyehudah Resp. 28.
