Semichas Raboseinu, a new sefer by Rabbi Menachem Mendel Kahn, Rosh Kollel Maayan Yisroel in Flatbush and a respected Torah publisher, has just been published. The sefer brings together all the rulings of our Rebbeim on the halachos of Issur v’Heter that are learned for semicha.

A new sefer, “Semichas Raboseinu”, has just been published by Rabbi Menachem Mendel HaKohen Kahn, Rosh Kollel Maayan Yisroel in Flatbush and a respected Torah publisher.

The sefer brings together all the rulings of our Rebbeim on the halachos of Issur v’Heter—beginning with the Maggid of Mezritch, through the Alter Rebbe, the Tzemach Tzedek, and subsequent Rebbeim. These are the halachos studied in the traditional “Semicha” track, learned by hundreds of Chabad bochurim and Yungerlait each year.

Rabbi Kahn’s first sefer, “Keset Sofer im Piski HaRav”, compiled the rulings of our Rebbeim on the halachos of STa”M, designed as a practical guide for Chabad sofrim to know the Halacha according to our mesorah. It achieved exceptional success—selling out twice, and now in preparation for a third edition.

In Semichas Raboseinu, Rabbi Kahn has invested meticulous effort in clarity, precision, and organization. The result is a volume that allows students to access the rulings of our Rebbeim on the key topics of Issur v’Heter with ease. It promises to become an indispensable resource for the hundreds of bochurim beginning their Semicha studies each year, while also enriching the broader Chabad bookshelf.

The sefer is now available at leading Judaica stores, and can also be purchased directly through the publisher’s website.
