One of the generation's leading poskim
Rabbi Asher Weiss — Rav Osher Weiss — is widely regarded as one of the foremost poskim of the present generation. Based in Jerusalem, he serves as av beis din and heads his kollel and beis din, Machon Minchas Osher, and his rulings are sought from around the world. He is especially known for his mastery of medical halacha, where doctors and hospitals turn to him with some of the most difficult and consequential questions a posek can face, and his responsa in this area are studied closely.
Beyond his role as a posek, Rav Weiss is a beloved teacher whose weekly shiur draws a large and devoted following. He is admired not only for the breadth of his knowledge but for the clarity and warmth with which he delivers it, making even intricate halachic analysis feel reachable. To learn his Torah is to sit with a mind that operates at the highest level of lomdus while never losing sight of the person asking the question.

The Minchas Osher seforim
Rav Weiss's teaching lives on in his celebrated Minchas Osher seforim — a wide-ranging body of work that has become a fixture in batei medrash. The series includes his volumes on the Chumash, where he brings deep, original insight to the parsha; his works on the moadim, the festivals; and his responsa on practical halacha across a vast range of contemporary questions. Together they capture both his conceptual approach to learning and his authority in psak.
What distinguishes the Minchas Osher is the marriage of depth and clarity. Rav Weiss is known for penetrating to the core principle of a sugya and then building outward with a structure a reader can follow, so that his seforim reward both the accomplished lamdan and the earnest learner reaching higher. For anyone drawn to serious halacha and machshava, his written Torah is among the most valuable of our time.
Why his Torah reaches so widely
Part of what has made Rav Weiss so influential is that his Torah meets the modern world without bending to it. His prominence in medical halacha places him at the frontier where ancient law meets new technology and hard human situations, and he addresses those questions with both rigor and deep sensitivity. Learners across the spectrum trust him precisely because he does not flinch from complexity and does not sacrifice the halacha to convenience.
That same quality carries into his shiurim and seforim on every subject. Whether he is opening a parsha, a Yom Tov, or a knotty question of practical law, he speaks as someone who has thought the matter through to its foundations and can hand a listener a way of seeing it whole. It is Torah of the highest caliber, offered in a voice that wants to be understood — which is much of why his following stretches so far beyond Jerusalem.
