Скачать или смотреть Business Halacha: The Five Inuyim of Yom Kippur — Torah or Rabbinic? | Rabbi Perlow

The Torah commands us on Yom Kippur to practice “Inui” — affliction, or more accurately, self-deprivation.
We all know the five inuyim:

Eating & drinking

Washing

Anointing

Wearing leather shoes

Marital relations

But here’s the halachic question:
👉 Are all five Biblical (d’Oraisa) — or is only eating/drinking Biblical, while the others are Rabbinic (d’Rabbanan)?

In this shiur, Rabbi Perlow examines:

How Chazal derived each of the five inuyim from the Torah.

Classic sources: the Rishonim who hold most are d’Rabbanan vs. the Ran and Rambam who hold they are d’Oraisa.

What it means that the Torah left the definition of Inui “open” for Chazal to define (Halacha l’Moshe mi’Sinai vs. Halacha l’Rabbanan).

Practical nafka minas (differences):

When exceptions are made (a king, a bride, a postpartum woman, children, someone dirty, medical needs).

The case of safek (doubt) — when must we be stringent?

Why the Magen Avraham, Mishnah Berurah, and others debate if the four non-eating inuyim are “true d’Oraisa” or a safek d’Oraisa.

This shiur provides deep background to understand why Yom Kippur feels the way it does halachically — and how Chazal shaped the experience of the holiest day of the year.
