In Egypt it was customary the custom was to bring musicians to play on the Sabbath of a circumcision. They would do this by inviting them from the Sabbath Eve, so that they could play on the Sabbath, and this is permitted by religious law. Despite the fact that our master Rabbi Ben Zimra wrote that …" in Egypt the custom was to forbid" to instruct a non-Jew to play music on the Sabbath itself, there is no prohibition to instruct the non-Jew on the Sabbath Eve. The prohibition given by our master Rabbi Ben Zimra in that Response does not apply in this case, and those who do so are not to be reprimanded. If there is, however, any suspicion that they will collude in hiring non-Jews to play on the Sabbath day itself, the right thing to do is to apply a safety margin on this matter as well.
