The Sefer HaMitzvot HaKatzar (Concise Book of Commandments) is an abbreviated reworking of Maimonides’ Sefer HaMitzvot that only includes commandments applicable outside of Israel in the post-Temple era, written by Rabbi Yisrael Meir HaKohen Kagan, author of the Mishnah Berurah and the Chafetz Chaim. In the work’s introduction, Kagan explained that he wanted his audience to be able to easily access a list of commandments applicable to their lives, and sifting through the Sefer HaMitzvot to isolate the relevant ones would be cumbersome.
