Separating Terumot and Ma\u2019asrot on Shabbat and Yom Tov"},"content":{"rendered":"
One may not separate terumot<\/em> and ma\u2019asrot<\/em> or \u1e25alla<\/em> on Shabbat. Separating them resembles an act of consecration, which is not performed on Shabbat. It also appears to make the produce fit for use: before the separation, the produce may not be eaten; through the separation, that restriction is removed and the produce becomes permitted. One may not redeem ma\u2019aser sheni<\/em> or neta reva\u2019i<\/em> on Shabbat either. If one mistakenly separated or redeemed on Shabbat, the produce may be eaten that Shabbat. If he did so intentionally, the separation or redemption is effective and the produce is permitted, but no Jew may eat from it until Shabbat ends. The same law applies on Yom Tov (SA, O\u1e24 339:4; 524:1; MB 339:25\u201326; \u1e24atam Sofer<\/em>, O\u1e24 79; below, 11:13).<\/p>\n If one is concerned that he will not manage to separate terumot<\/em> and ma\u2019asrot<\/em> before Shabbat from produce intended for Shabbat, he may prepare for this before Shabbat. He does so by reciting the nusach<\/em> for separating terumot<\/em> and ma\u2019asrot<\/em>, without a berakha, in the future tense, referring to the produce he will separate on Shabbat. This begins the process of separation before Shabbat. He may then complete the separation on Shabbat using the regular nusach<\/em> and recite the berakha. The same method may be used by one who is concerned that he will not manage to separate \u1e25alla<\/em> before Shabbat.[1]<\/a><\/sup><\/p>\n Only the owner of the produce can use this method, because only he can begin the separation before Shabbat and complete it on Shabbat. A guest who is concerned that his host may forget to separate terumot<\/em> and ma\u2019asrot<\/em> should ask the host before Shabbat to appoint him as his agent for this purpose. Once appointed, the guest may begin the separation before Shabbat on the host\u2019s behalf and complete it on Shabbat (Mishna<\/em>, Demai<\/em> 7:1, 5; Yerushalmi<\/em>, Demai<\/em> 7:1; MT, Laws of Ma\u2019aser 9:7\u20139).[2]<\/a><\/sup><\/p>\n
