==General Obligation to Say Korbanot==
# For someone who doesn't have enough time to recite all of the Korbanot, here is a list of the order of importance: Lefikach Anachnu Chayavim until Mekadesh Shemo BeRabim, Yehi Ratzon… SheTerachem, Parshat Tamid, Parshat Ketoret until Rabbi Natan HaBavli, Yehi Ratzon SheYehe Siach Sifatenu… KeHilchato.<ref>Avnei Yashfeh (pg 118)</ref> Some say that the korbanot take precedence over Mizmor Chanukat Habayit.<ref> Siach [[Tefilla]] (pg 637)</ref>
# Some say that a Talmid Chacham doesn't have to recite the paragraph of the Akeda,<ref>Piskei Teshuvot 1:16 writes that since the Shulchan Aruch 1:5 only stated that it is proper for a person to recite the parsha of Akeda, Maan, Aseret Hadibrot, and paragraphs of Korbanot and it isn't a formal obligation, someone who “makes Torah his occupation” and does not waste time can skip them and learn instead. (He bases this on the Mishna Brurah 1:12 and Kaf Hachaim 1:31 who are not dealing with this and rather dealing with non-standard additions to davening that a Talmid Chacham is exempt from.)</ref> while most disagree.<ref>Yalkut Yosef 1:26 writes that a Talmid Chacham and certainly a Yeshiva student should say Parshat Akeda. Or Letzion 2:7:1 seems to agree.</ref># Some say that someone who learns Gemara anyway can skip Aizhu Mekoman and the Briatta of Rabbi Yishmael.<ref>Tefilla KeHilchata (pg 185) quotes Rav Elyashiv saying that someone who learns anyway saying Aizhu Mekoman and Briatta DeRabbi Yishmael is proper but not obligatory.</ref>
Others disagree.<ref>Or Letzion 2:7:1 writes that even a Talmid Chacham isn't exempt from Aizhu Mekoman since it isn't just another section of Torah; it is a fulfillment of bringing Korbanot with our lips. He adds that the Briatta of Rabbi Yishmael also has lofty meanings attached to it and therefore even a Talmid Chacham should recite it.
* See Halichot Shlomo (Tefillah, chap 6 note 20, pg 76-7) where the practice of Rav Shlomo Zalman Auerbach is recorded. He would arrive at shul 10 minutes early and say Birchot HaShachar, the paragraph before Akeda (Elokenu VeElokey until KaKatuv Betoratach), LeOlam Yehe Adam (until the end), Korbanot, and Ketoret. [It seems clear that he only said the introductory paragraph to the Akeda and not the Parshat Akeda itself.]</ref>
# The paragraphs of the korbanot, including the Olah, Mincha, Shlamim, etc do not have to be recited on Shabbat but can be. A Talmid Chacham should preferably learn the parsha instead.<ref>Magen Avraham 1:11 and Mishna Brurah 1:17 quote the Shlah that one can say the specific paragraphs of Olah, Mincha, Shlamim, etc on Shabbat but there is no obligation to do so. Therefore, a Talmid Chacham should preferably study the parsha of the day instead of saying these Korbanot. However, the Maharam Nigrin (quoted by the Knesset HaGedolah 1:1) says that the Korbanot do not need to be said on [[Shabbat]].</ref> Either way, the practice today is that no one recites these paragraphs at all and they are replaced with the recital of Eizhu Mekoman.<Ref>Halacha Brurah 1:15, Piskei Teshuvot 1:16</ref>
