The Rambam lists eight structural requirements for Kosher Tefillin, from their square shape to their stitching, all transmitted as Halacha Moshe Mi'Sinai. This Perek walks through each requirement and what happens when even one is not met.

Perek ב: Writing the Parshiyot of Tefillin
How exactly are the four passages inside Tefillin written? This Perek details the precise spelling, order, and layout of the Parshiyot for both the head and arm Tefillin, including the letters that require special crowns, and explains why any deviation disqualifies the Tefillin entirely.

Perek א: The Sanctity of the Written Word
This opening Perek introduces the five Mitzvot at the heart of this section: wearing Tefillin on the head and arm, affixing a Mezuzah, and writing a Torah scroll. It lays down the foundational rules for any sacred scribe, who may write these texts, the intent required when inscribing HaShem's name, and why a single flawed letter can invalidate the entire article.

The structure of Kriyat HaTorah takes center stage here: the required times for public reading, who is called to the Torah and in what order, and the rules that keep this cornerstone of communal life running smoothly.

Perek י״א: Building a 'House for Prayer'
Every community needs its own Shul. This Perek explores the Halachic requirements for building one, its ideal location and structure, and the layer of sanctity that transforms a physical building into a place set apart.

Perek י: When Things Go Wrong
Mistakes happen mid-Tefilla, so what then? This Perek works through the practical rules for errors in the Amidah, when the individual or the Chazzan must go back and repeat, and how missed Tefilla can sometimes be made up later.
