Source for Avraham failing his test at the Akeida?

Question

In a recent interview on Times of Israel, Rabbi Nathan Lopez Cardozo says that he is of the opinion that Avraham failed his test at the Akeida:

I am of the opinion that Abraham, by being prepared to do so, to sacrifice his son, failed the test. I think that the reading of the binding of Isaac should be different from the conventional approach as some chassidic texts indeed seem to suggest. For an excellent overview read: The Fear, the Trembling and the Fire by my dear friend, Professor Jerome (Yehudah) I. Gellman, published by University Press of America in 1994.

Aside from the book that Rabbi Cardozo references, what are the Jewish sources that Rabbi Cardozo may be drawing upon (i.e. Talmud, Rishonim, Achronim, later source, etc.)?

Answer 1

Rabbi Cardozo quotes Professor Gellman's book“The Fear the Trembling and the Fire”.

I do not have the book but the link above provides an excerpt. This quotes (p 23):

Rabbi Mordechai Yosef Leiner of Izbica (also known as the Izbitzer) and his work מי השילוח.

Gellman writes that “The 'Izbicer' became known for his novel and sometimes daring readings of Scriptures.”

Other Jewish sources mentioned are

“Saadia”, but it is not clear which Saadia this is.

The book also says that the Ralbag's commentary on the Torah is the closest precedent to the Izbicer's version.
