Rambam In-Depth: Why Did the Rambam Omit Aba Shaul's Opinion?

🌳 Welcome to Rambam In-Depth 🌳

Join us for an fascinating exploration of Rambam’s Hilchos Shchenim (Perek Yud, Halacha Aleph), where we examine a perplexing omission in the Mishneh Torah and discover profound insights about halachos that apply in different eras.

🔍 The Question: The Rambam rules that trees must be distanced at least 25 cubits from the city (50 cubits for carob and fig trees). The Gemara in Bava Basra quotes Aba Shaul’s opinion that non-fruit-bearing trees (ilan srak) require 50 cubits distance. In his Peirush HaMishnayos, the Rambam explicitly rules “halacha k’Aba Shaul” - yet he completely omits this halacha from the Mishneh Torah. Why?

📚 Topics Covered:

• The basic halacha of distancing trees from the city (מרחיקין את האילן)
• Tosefos Yom Tov’s question on the Rambam’s omission
• The Nimukei Yosef on hilchos l’Moshiach
• The Chasam Sofer’s brilliant answer about future irrelevance
• Rabbi Galinsky’s challenge regarding the first tekufa of Moshiach
• The Rebbe’s explanation from Likutei Sichos (Chelek 27, Bechukosai)
• The distinction between changes in Eretz Yisroel vs. worldwide
• Rav Kapach’s version and the Rambam’s position change
