1) Every morning, before Shacharis, we say the Tefilah of “Adon Olam Asher Malach…” [Master of the world, who reigned before anything was ever created…] The Tefilah of Shacharis was instituted by our patriarch Avraham Avinu, who was the first person to refer to Hashem as “Adon” [Master of the world], thus it is appropriate to praise Hashem in the morning with the title “Adon”.
The Eliyah Rabbah [quotes earlier Poskim who say] that one who concentrates on the[meaning of the] words of Adon Olam while saying it, will merit having his prayers answered, and the Satan will not get in the way of having his prayers go up directly to heaven.
2) It is praiseworthy to recite the Parsha of the Akeidas Yitzchak daily [before reciting the Parsha of Karbanos], as to invoke the merit of our forefathers each day before we begin to pray.
It is also advisable to say the Parsha of the Man [that fell in the desert], to strengthen our belief that each person’s daily sustenance comes directly from Hashem with Hashgacha Pratis (divine providence). In fact, Chazal say that one who reads this Parsha [of the Man] daily, is guaranteed that his daily bread (i.e. sustenance) will not be lacking. (The Seforim bring in the name of Rabeinu Tam to say the Pesukim of the Parsha of the Man Twice followed by the Targum once, as doing so is extremely Mesugal (beneficial) for Parnassah.) The prevalent Minhag for those who say the Parshas Haman is to do so after the completion of Shacharis, and not before davening. (Most Siddurim today have it printed at the end of davening as well)
