Level 4 — Daat HaRav (Alter Rebbe) — Siman קצ״ו · מִי שֶׁאָכַל דְּבַר אִסּוּר אִם מִצְטָרֵף לְזִמּוּן

The Alter Rebbe’s way on מִי שֶׁאָכַל דְּבַר אִסּוּר אִם מִצְטָרֵף לְזִמּוּן : אֵין מְזַמְּנִין עַל אוֹכֵל אִסּוּר ; שׁוֹגֵג וּמֵזִיד בְּבִרְכַּת הַמָּזוֹן ; גָּזַל לֶחֶם אָפוּי ; קִנְיַן שִׁנּוּי בַּפַּת ; אִסּוּר בִּמְקוֹם סַכָּנָה ; פַּת נָכְרִי וְחַלָּה ; בָּשָׂר וּגְבִינָה וּמֻדָּרִים הֲנָאָה — in the Habad sensibility.

Why a Level 4 devoted to the Alter Rebbe ? The Alter Rebbe’s Shulchan Aruch is not a commentary on the Mehaber (מחבר) — it is a complete, self-standing Shulchan Aruch, written by the Alter Rebbe (Rabbi Schneur Zalman of Liadi, founder of Habad, disciple of the Maggid (מגיד) of Mezeritch). Its singularity : it combines halakha (הלכה) + טעמי המצוות + inner dimension in one work, and rules with a unique Talmudic rigor.

For Habad, the Alter Rebbe is הפוסק האחרון — his psak is the deciding authority. This page gathers the Rav’s way on siman קצ״ו — מִי שֶׁאָכַל דְּבַר אִסּוּר אִם מִצְטָרֵף לְזִמּוּן (one who ate forbidden food: does he join the zimun?), which unfolds in the Rav over ז׳ סְעִיפִים (seven seifim) : from the refusal of zimun for one who ate a prohibition — even a merely rabbinic one — and the dispute over the blessing itself, decided by the division of shogeg and mezid, to already-baked bread that was stolen, where only the final blessing stands, to stolen wheat that shinui makes his own, to the standing of the other guests, to a prohibition eaten in peril of life which is a mitzvah and no fault, up to the joining of those whose breads exclude one another — pat nokhri and challah, meat and cheese, mudar hana’ah — where everything turns on a single question: could they have eaten one bread?

מִי שֶׁאָכַל דְּבַר אִסּוּר אִם מִצְטָרֵף לְזִמּוּן, וּבוֹ ז׳ סְעִיפִים:

One who ate a forbidden food — whether he joins the zimun; and it comprises seven seifim. One who ate a forbidden thing — even if it is forbidden only by the words of the Soferim (a rabbinic prohibition) — we do not make zimun over him.
And some say that likewise he does not recite birkat hamazon after it, even if he ate inadvertently (be-shogeg), for a transgression is no mitzvah. And if he knows that it is forbidden and comes to eat it nonetheless — he does not bless over it at the outset, for such a man does not bless: he reviles, as it is written: “uvotzea berekh — ni’etz Hashem” (he who takes his gain and blesses reviles Hashem).
And some say that this was said only of a mitzvah that comes through a transgression, over which it is unfitting to mention the Name of Heaven and over which one does not recite birkat hamitzvot, for a transgression is no mitzvah; but a blessing over enjoyment (birkat hanehenin) he must recite — even one who eats Torah prohibitions deliberately (be-mezid). For one who eats garlic and whose breath reeks — shall he go back and eat another garlic so that his breath reek the more? And shall he likewise take enjoyment of this world without a blessing? They withheld nothing but the making of zimun over him, because his companions are not permitted to associate with him in a company. And a company all of whom ate forbidden things likewise have no fixity (keva), for there is neither fixity nor association for forbidden things; and this resembles the eating of fruit, which has no fixity for zimun. But the blessing at the outset and at the end — why should he not recite it? Since he has taken enjoyment.
And as to the halakha, one should decide that if he ate a prohibition inadvertently — he blesses afterward; but the mezid blesses neither at the outset nor at the end, for such a man does not bless: he reviles.
Explanation. Three positions follow one another, and the Rav orders them. The first denies the offender even the blessing itself: a transgression cannot yield a mitzvah. The second separates the registers — birkat hamitzvot honors an act, birkat hanehenin discharges a pleasure already taken — and the image of the garlic says everything: adding a fault to a fault erases nothing, and one does not leave this world unblessed. The Rav decides by the division of shogeg and mezid: inadvertence leaves the final blessing standing, deliberation turns it into revilement. The refusal of zimun rests on none of these grounds: it holds because the company itself is illicit.

סעיף ב גָּזַל לֶחֶם אָפוּי — "אֵינוֹ מְבָרֵךְ עָלָיו בַּתְּחִלָּה".

אִם גָּזַל אוֹ גָּנַב לֶחֶם אָפוּי, אַף עַל פִּי שֶׁכְּבָר נִתְיָאֲשׁוּ הַבְּעָלִים — אֵינוֹ מְבָרֵךְ עָלָיו בַּתְּחִלָּה, לְפִי שֶׁאִם הָיוּ הַבְּעָלִים בָּאִים לְתָבְעוֹ מִמֶּנּוּ — הָיָה חַיָּב לְהַחֲזִירוֹ לָהֶם, וְלֹא הָיָה יָכוֹל לִפְטֹר אֶת עַצְמוֹ בְּדָמִים, נִמְצָא שֶׁאֲכִילָתוֹ הִיא בַּעֲבֵרָה, וּבִרְכָתוֹ נִאוּץ. אֲבָל מְבָרֵךְ אַחֲרָיו בִּרְכַּת הַמָּזוֹן, שֶׁכְּשֶׁכְּבָר אֲכָלוֹ הוּא שֶׁלּוֹ, וְדָמִים הוּא חַיָּב לוֹ. וְאַף שֶׁאָכַל בְּאִסּוּר, כֵּיוָן שֶׁאַחַר הָאֲכִילָה יָכוֹל לִפְטֹר אֶת עַצְמוֹ בְּדָמִים שֶׁיְּהֵא מַה שֶּׁאָכַל שֶׁלּוֹ — אֵין בִּרְכָתוֹ אָז נִאוּץ:

If he robbed or stole already-baked bread, even though the owners have already despaired of it (ye’ush) — he does not bless over it at the outset, because if the owners came to claim it from him he would be bound to return it to them and could not discharge himself with money; it turns out, then, that his eating is a transgression and his blessing revilement. But he does recite birkat hamazon after it, for once he has eaten it, it is his, and it is money that he owes. And although he ate in prohibition, since after the eating he can discharge himself with money so that what he ate be his — his blessing is then no revilement.
Explanation. The Rav’s criterion is not sentiment but title: so long as the object can be returned in kind, it remains another’s, and eating it is a transgression in act — hence no blessing beforehand. The act of eating consumes the object itself: what remains is a debt of money only, and a debt of money does not taint the final blessing.

סעיף ג גָּזַל חִטִּים וְאָפָה פַּת — "קְנָאוֹ בְּשִׁנּוּי".

אִם גָּזַל חִטִּים אוֹ קֶמַח וְאָפָה פַּת — מְבָרֵךְ גַּם בַּתְּחִלָּה, שֶׁכְּבָר קְנָאוֹ בְּשִׁנּוּי וְנַעֲשָׂה שֶׁלּוֹ, שֶׁאִם בָּאוּ הַבְּעָלִים יָכוֹל לִפְטֹר אֶת עַצְמוֹ בְּדָמִים, וְאֵין אֲכִילָתוֹ עֲבֵרָה. וְאַף עַל פִּי שֶׁכַּיּוֹצֵא בָּזֶה בְּמִצְוָה אֵינוֹ מְבָרֵךְ עָלֶיהָ, הוֹאִיל וּמִכָּל מָקוֹם עַל יְדֵי עֲבֵרָה בָּאָה לְיָדוֹ, כְּמוֹ שֶׁנִּתְבָּאֵר בְּסִימָן י״א - אֵין לְדַמּוֹת בִּרְכַּת הַנֶּהֱנִין לְבִרְכַּת הַמִּצְוֹת, מִטַּעַם שֶׁנִּתְבָּאֵר בַּסְּבָרָא הָאַחֲרוֹנָה שֶׁבִּסְעִיף א׳. וְאַף לַסְּבָרָא הָרִאשׁוֹנָה אֵינָן דּוֹמוֹת אֶלָּא כְּשֶׁנֶּהֱנָה בַּעֲבֵרָה, וְלֹא כְּשֶׁבָּאוּ עַל יְדֵי עֲבֵרָה. וְיֵשׁ חוֹלְקִין בָּזֶה (וּסְפֵק בְּרָכוֹת לְהָקֵל):

If he stole wheat or flour and baked bread from it — he blesses at the outset as well, for he has already acquired it through change (shinui) and it became his, so that were the owners to come he could discharge himself with money, and his eating is no transgression. And although in a comparable case concerning a mitzvah he does not bless over it — since nonetheless it came into his hand through a transgression, as was explained in siman י״א — one does not compare birkat hanehenin to birkat hamitzvot, for the reason set out in the last view in seif א. And even according to the first view they are comparable only where he takes enjoyment through the transgression, and not where they came into his hand through a transgression. And some dispute this (and in doubt concerning blessings one is lenient).
Explanation. The shinui — wheat become bread — effects a transfer of title: what the thief eats is now his own, and the obstacle of the preceding seif falls of itself. There remains the objection drawn from a mitzvah that comes through a transgression (siman י״א); the Rav defuses it on two levels: first by refusing the analogy between the two registers of blessing, then, should the analogy be maintained, by distinguishing enjoying through the fault from receiving through the fault. One view keeps disputing: the closing parenthesis settles it by safek berakhot lehakel.

סעיף ד אֲחֵרִים מְבָרְכִין "לְדִבְרֵי הַכֹּל".

וְכָל זֶה בְּגַנָּב וְגַזְלָן עַצְמוֹ, אֲבָל אֲחֵרִים מְבָרְכִין בַּתְּחִלָּה וּבַסּוֹף לְדִבְרֵי הַכֹּל, שֶׁהֲרֵי לֹא עַל יְדֵי עֲבֵרָה בָּאָה לְיָדָם, אֶלָּא אִם כֵּן גָּנַב לֶחֶם אָפוּי וְלֹא נִתְיָאֲשׁוּ הַבְּעָלִים, כְּמוֹ שֶׁיִּתְבָּאֵר בְּסִימָן תרמ״ט:

And all this concerns the thief and the robber themselves; but others bless at the outset and at the end according to all views, for it did not come into their hand through a transgression — unless he stole already-baked bread and the owners have not despaired of it, as will be explained in siman תרמ״ט.
Explanation. The disqualification is personal and does not attach to the food: the guest who has done nothing blesses without reserve. The one exception is where the object remains another’s property — baked bread, without ye’ush — for then no one can derive title from it, and the matter is referred to siman תרמ״ט.

סעיף ה אָכַל אִסּוּר "בִּמְקוֹם סַכָּנָה" — מְבָרֵךְ.

אִם אָכַל אִסּוּר בִּמְקוֹם סַכָּנָה, לְדִבְרֵי הַכֹּל מְבָרֵךְ עָלָיו תְּחִלָּה וָסוֹף, שֶׁהֶתֵּר הוּא אוֹכֵל, וּמִצְוָה הוּא עוֹשֶׂה לְהַצִּיל נַפְשׁוֹ:

If he ate a prohibition in a place of danger, according to all views he blesses over it at the outset and at the end, for it is permitted food that he eats, and it is a mitzvah that he performs in saving his life.
Explanation. Peril does not merely excuse the prohibition: it changes its very qualification. The food is not a tolerated prohibition, it is permitted — and the act is not a mitigated fault, it is a mitzvah. Nothing therefore stands in the way of the blessing, and the two views of seif א agree here.

סעיף ו פַּת נָכְרִי וְחַלָּה — "הוֹאִיל וְהִיא מֻתֶּרֶת לוֹ".

שְׁלֹשָׁה שֶׁאָכְלוּ כְּאַחַת וְאֶחָד מֵהֶם אָכַל פַּת נָכְרִי וְהַשְּׁנַיִם נִזְהָרִים מִמֶּנּוּ, אוֹ שֶׁאֶחָד מֵהֶן כֹּהֵן וְאָכַל חַלָּה, אַף עַל פִּי שֶׁהִיא אֲסוּרָה לְהַשְּׁנַיִם — מְזַמְּנִין עָלָיו, הוֹאִיל וְהִיא מֻתֶּרֶת לוֹ.
וְאִם הָיוּ כֹּהֲנִים עִם זָר אוֹכְלִין כְּאֶחָד וְהַזָּר אוֹכֵל פַּת נָכְרִי וְהַכֹּהֲנִים נִזְהָרִים מִמֶּנָּה וְאוֹכְלִים חַלּוֹת — אֵינָן מִצְטָרְפִין לְזִמּוּן, שֶׁכָּל צֵרוּף לְזִמּוּן אֵינוֹ אֶלָּא כְּשֶׁהֵם יְכוֹלִים לְהִתְחַבֵּר יַחַד בַּאֲכִילָתָם לֶאֱכֹל לֶחֶם אֶחָד, וְכָאן כָּל אֶחָד נִזְהָר מִלֶּחֶם חֲבֵרוֹ.
(מַה שֶּׁאֵין כֵּן כְּשֶׁהַזָּר אֵינוֹ אוֹכֵל פַּת שֶׁנִּזְהָר מִמֶּנָּה הַכֹּהֵן שֶׁאוֹכֵל חַלָּה, אַף שֶׁהַזָּר אֵינוֹ יָכוֹל לֶאֱכֹל מִלַּחְמוֹ שֶׁל כֹּהֵן, כֵּיוָן שֶׁהַכֹּהֵן יָכוֹל לֶאֱכֹל מִלַּחְמוֹ שֶׁל יִשְׂרָאֵל, אוֹ הַשְּׁלִישִׁי שֶׁאוֹכֵל פַּת נָכְרִי יָכוֹל לֶאֱכֹל עִם הַשְּׁנַיִם — מִצְטָרְפִים):

Three who ate together, and one of them ate the bread of a non-Jew (pat nokhri) while the two are careful of it; or one of them is a kohen and ate challah, although it is forbidden to the two — we make zimun over him, since it is permitted to him.
And if kohanim were eating together with a zar (a non-kohen), the zar eating pat nokhri and the kohanim being careful of it and eating challot — they do not join for zimun, for all joining for zimun exists only where they can associate together in their eating so as to eat one bread, and here each is careful of his fellow’s bread.
(Not so where the zar does not eat bread of which the kohen who eats challah is careful: even though the zar cannot eat of the kohen’s bread, since the kohen can eat of the Israelite’s bread; or where the third, the one who eats pat nokhri, can eat with the two — they join.)
Explanation. Zimun is measured not by what each in fact ate but by what they could have eaten together. A guest whose food is forbidden to the others remains joinable so long as a shared bread stays possible in at least one direction. The impediment is complete only when each is careful of the other’s bread: the table is then shared without being common, and the tzeruf falls away.

Likewise, one eats cheese and two eat meat — they join, for the one who eats cheese can eat of their bread even though it is soiled with meat, if he wipes his mouth and rinses it (kinuaḥ and hadaḥah). But if he eats hard cheese — they do not join, for the custom nowadays is not to eat meat after hard cheese by means of wiping and rinsing.
Likewise, at a seudat mitzvah from Rosh Ḥodesh Av until Tisha be’Av, where some of the invited eat cheese, as will be explained in siman תקנ״א: since they refrain from meat by reason of the custom — they do not join with those who eat meat, and must make zimun by themselves; unless they ate a kezayit of bread before those who eat meat began to eat meat with their bread — for that kezayit they could have eaten of his bread; or unless one of the company ate a kezayit of other bread soiled neither with meat nor with milk, for such a one joins them all, since all can eat of his bread.
Likewise, three who are bound by vow from benefiting one from another (mudar hana’ah), or even one bound with respect to the two and the two with respect to him: although they can have their vow annulled, so long as they have not had it annulled — they do not join, if each eats of his own. But if they eat of the householder’s — they join (for it is the way of a householder to feed his guests bread as much as they need; and if so, even if this one eats of a slice that that one cut for himself, he takes enjoyment only of what belongs to the householder, since that one’s bread will not thereby be diminished. Not so those who eat meat and cheese, who cannot eat one from the slice the other cut: even though each could cut himself a slice from one loaf, particularly before they touched meat and milk — this does not suffice to associate and join them, for what difference is there to me between separate loaves and one loaf?)
Explanation. A single criterion runs through all three cases: joinable is he who could eat of the table’s bread. Soft cheese leaves that possibility open through kinuaḥ and hadaḥah; hard cheese closes it, custom here having the force of rule. The kezayit eaten before meat touched the bread, or the kezayit of neutral bread eaten by a third party, restores the bond because it restores the common bread. And the vow of hana’ah is undone not by the possibility of annulment but by the provenance of the bread: what comes from the householder is no one’s property at that table, and no one there takes anything from another.

2 · למעשה

הלכה למעשה — מנהג חב״ד

The practical Habad conduct

Points of conduct that follow directly from siman קצ״ו in the sensibility of the Alter Rebbe and Habad — presented at the level of principle, referring to the Rav for the detail of cases.

For the Habad Hassid — Siman קצ״ו (מִי שֶׁאָכַל דְּבַר אִסּוּר אִם מִצְטָרֵף לְזִמּוּן)

  • ① Seif א. One who ate a prohibition — even a merely rabbinic one — is not included in zimun: his companions are not permitted to form a company with him, and a company all of whom ate what is forbidden likewise has no keva. On the blessing itself the Rav decides: inadvertently (shogeg), one blesses afterward; deliberately (mezid), one blesses neither before nor after.
  • ② Seif ב. Already-baked bread, stolen: even after the owners’ ye’ush, no blessing beforehand — the object is still returnable in kind. But birkat hamazon afterward, since the eating has turned restitution into a mere debt of money.
  • ③ Seif ג. Wheat or flour stolen and then baked into bread: the shinui acquires it, and one blesses beforehand as well. The rule of a mitzvah that comes through a transgression (siman י״א) is not transposed here: birkat hanehenin and birkat hamitzvot are not comparable. One view disputes it — and doubt in matters of blessings is resolved leniently.
  • ④ Seif ד. All this holds only for the thief himself. The other guests bless before and after according to all views — except where the bread was already baked and stolen without the owners’ ye’ush (siman תרמ״ט).
  • ⑤ Seif ה. A prohibition eaten in peril of life: a blessing before and after, according to all views. It is not a tolerated prohibition, it is permitted food — and saving one’s life is a mitzvah.
  • ⑥ Seif ו. A guest who eats pat nokhri of which the others are careful, or a kohen who eats challah forbidden to the others: zimun is made over him, for his bread is permitted to him. But where each is careful of the other’s bread — kohanim with challot, a zar with pat nokhri — there is no tzeruf: zimun presupposes that they could eat one bread.
  • ⑦ Seif ז. Cheese and meat at one table: tzeruf so long as kinuaḥ and hadaḥah suffice — hence not with hard cheese. In the days from Rosh Ḥodesh Av to Tisha be’Av (siman תקנ״א), those who eat cheese make zimun by themselves, unless they ate a kezayit of bread before the others began the meat, or unless a guest ate a kezayit of neutral bread, which joins them all. Mudar hana’ah: no tzeruf so long as the vow is not annulled, if each eats of his own; but if they eat of the householder’s bread — tzeruf.

⚠ This section presents the Habad conduct grounded in the Alter Rebbe’s Shulchan Aruch, siman קצ״ו (the real text reproduced in §1). It does not replace a rabbinic decision for a particular case. For any concrete question — the blessing after forbidden food, stolen bread, the joining of guests whose breads exclude one another, meat and cheese between Rosh Ḥodesh Av and Tisha be’Av — consult your Rav, and for Habad, a Habad Rav.
