Rafi Magid asked:
who is the "rav hovel" mentioned in Tosfos?
The Kollel replies:
Some explain that Tosfos is referring to the Rambam, although it does not seem likely that Tosfos would refer to the Rambam in such a way. In addition, the Rambam does not say all of what Tosfos quotes him as saying. Therefore, it remains a doubt to whom Tosfos refers.
