Is it a mitzvah to eat the fruits of shmitta? Who holds yes? Who holds no and why?
The Torah tells us that the fruits of the seventh year are “for eating”. The Ramban is his commmentary on the Rambam’s Sefer Hamitzvos has a list of Mitzvos he holds the Rambam overlooked. The third one is that which Chazal learn from the above pasuk that the fruits of the seventh year are “for eating” and not for doing business.
The commentary of the Megilas Ester thee seems to understand that there is a dispute between the the Rambam and Ramban as to whether there is a mitzvah to eat the fruits of Shviis. The Chazon Ish however, disagrees. He is of the opinion that even the Ramban holds there is no mitzvah to eat the seventh year fruit. The intent of the Ramban is that the prohibition against doing business should be counted as a mitzvah.
