Quotation על בראשית 26:41

And behold they of blessed memory stated "'Inasmuch as Abraham obeyed me and kept my charge..." to teach us that our father Abraham, peace be upon him, kept even [the mitzvah] of Joining the Cooked Foods" which on the surface is confusing for how could he have known to do so? And if we say that he perceived [himself] the actions of the Commandments and the Laws to which the [human] intellect can bind, nevertheless its difficult [to understand] how he could have perceived the Decrees which have no reasoning [behind them] to which the [human] intellect cannot bind, like the Red Hefer and other such Decrees. Our discussion will be understood according the the words of our blessed Sages who stated, "to you I will reveal the reason behind the Red Hefer and the others will be Decrees (without reason)" for all the Decrees do [in fact] have a reason and a source above in the order of the creation, for the creation occurred in accordance with the Torah, its just that 'no [human] mind can contain it' - and [this is the meaning of] "...the others will be Decrees". However, the Torah does not speak to 'great ones' such as Moshe or our father Abraham, peace be upon them, before whom nothing stood as a Decree [without reason]; rather all the Decrees to them were Commandments in their understanding and they perceived their reasoning and source.
