[Avodah] non-existent midrashim

[Ben Waxman]

Professor Wikipedia notes the following in an article on the 
authenticity of the Zohar:

R' Menachem Mendel Kasher in an article in the periodical Sinai refutes 
many of Scholem's points. He writes:

Many statements in the works of the Rishonim (medieval commentators who 
preceded De Leon) refer to Medrashim that we are not aware of. He writes 
that these are in fact references to the Zohar.
