Tefillah - d'oraysa or derabbanan?
The Rambam's opinion is that tefilla is a mitzvah d'oraysa, while the Ramban disagrees. One of the proofs against the Rambam's position (discussed by the Sha'agas Arye #15) is the Mishna in Brachos (20b) which states that a ba'al keri must think (hirhur) the words of keriyas shema and bentching even if he cannot say them because of his state of tumah, but he can skip tefilla. The difference would seem to be that that shma and bentching are d'oraysa mitzvos, while tefilla is not - which of course, is contrary to the Rambam's position.
