1. The central axiom
Siman של"ז in one sentence.
The siman states a great principle of Shabbos: דבר שאין מתכוון מותר — a permitted act that could bring about a melachah remains permitted, as long as one does not intend it. Decisive exception: the פסיק רישיה — when the melachah is inevitable, the lack of intention no longer saves it. Housework is merely the field of application.

2. The key concepts condensed
| Concept | Definition | Application in the siman |
|---|---|---|
| דבר שאינו מתכוון | Unintended act | Permitted — dragging furniture, sprinkling water (seif א) |
| פסיק רישיה | Inevitable consequence | Forbidden — rolling a heavy barrel (seif ד) |
| השוואת גומות | Leveling the ground depressions | The underlying melachah (choresh / boneh) |
| כיבוד הבית | Sweeping the house | Paved / unpaved floor; strict custom (seif ב) |
| מלאכת מחשבת | Calculated, willed work | Why the unwilled act is not a melachah |
3. Hierarchy of cases
Permitted: an unintended act whose melachah is not certain — dragging a bed, a chair, a bench; sprinkling the house with water.
↓
Permitted under condition / custom: sweeping a paved floor (Mechaber permits it; Ashkenazi custom to refrain); sweeping with a light cloth or via a non-Jew.
↓
Forbidden: sweeping an unpaved floor; coating or washing the floor, even when paved.
↓
Forbidden (pesik reisha): rolling a heavy barrel that will certainly level the depressions.
4. Decision tree
Q1 — Is my act permitted in itself? (dragging, sprinkling) Yes → continue.
↓
Q2 — Could it bring about a melachah (leveling a depression)? No → permitted. Yes → continue.
↓
Q3 — Is this melachah certain? No, only possible → permitted (I do not intend it). Yes, inevitable → פסיק רישיה, forbidden.
↓
Q4 — Sweeping / cleaning the floor? → follow your community's custom. Doubt → consult your Rav.
5. The line of the פסיק רישיה — when the act tips over
The whole siman rests on a single hinge: the same gesture — dragging an object, sprinkling the floor, rolling a weight — is permitted or forbidden depending on whether the melachah it could cause (leveling a depression, השוואת גומות) is merely possible or certain. The delicate point is not the principle, but the precise line of the boundary.
Borderline case 1 — the heavy piece of furniture. Dragging a bed or a bench is permitted (seif א): on most floors, the object digs nothing for certain. But the same bench, on loose earth where it will inevitably leave a groove, becomes a פסיק רישיה — forbidden, although one intends only to move the furniture.
↓
Borderline case 2 — the barrel (seif ד). The Mechaber isolates it precisely because it is massive: its weight guarantees the leveling of the ground. This is no longer a doubt, it is an inevitable consequence — non-intention no longer saves it.
↓
Borderline case 3 — sprinkling water (seif א). Permitted: the water does not level the ground by itself. But spreading this water or packing the mud rejoins בונה — the act tips over as soon as it builds.
The underlying reasoning. Why does certainty change everything? Because the Torah forbids only a מלאכת מחשבת — a willed work. As long as the melachah is uncertain, the mind does not attach to it: it is not "calculated." But when it is unavoidable, willing the act amounts to willing its result: intention rejoins effect, and the prohibition reclaims its rights. The practical question thus always comes down to one: "is this effect guaranteed, or merely feared?"
Sorting criterion. Ask yourself not "did I want the melachah?" but "could the melachah have not occurred?". If yes — the act is permitted. If no — it is a פסיק רישיה, forbidden despite the absence of intention.
6. Mnemonic
אֵין — אֵינוֹ מִתְכַּוֵּן: I do not intend the melachah → permitted.
יֵשׁ — יֵשׁ פְּסִיק רֵישֵׁיהּ: the melachah is certain → forbidden, despite the absence of intention.
→ Two conditions to permit: no intention and no certainty.
7. Pitfalls to avoid
Pitfall 1 — "I did not want it, so it is permitted." False if the melachah is inevitable: a pesik reisha remains forbidden even without intention.
Pitfall 2 — confusing a light piece of furniture with a heavy object. Dragging light furniture: the melachah is not certain → permitted. A heavy barrel: it is certain → forbidden.
Pitfall 3 — sweeping out of habit. On an unpaved floor it is forbidden; and the Ashkenazi custom refrains even on a paved floor. Know your community's minhag.
Pitfall 4 — washing the floor "because it is tiled." Coating or washing the floor is forbidden even when paved (seif ג).
8. Modern practical cases
| Situation | Reference | Conduct |
|---|---|---|
| Sweeping the floor of the house | Seif ב | According to the minhag; many permit on hard tiling — consult your Rav |
| Moving a table or chair | Seif א | Permitted (unintended act) — no problem on a hard floor |
| Washing the floor, mopping | Seif ג | Forbidden, even on tiling |
| An act that could cause a melachah | Seifim א, ד | Permitted if the melachah is only possible; forbidden if certain |
