Chapter 44: 10-12
Reciting Grace after Meals10. [On a Sabbath, the prayer R'tzey (May it please You...) is addedto the third blessing of grace. On Rosh Chodesh, a festival, or aChol Hamo'ed, the prayer Ya'aleh v'yovo (May there ascend, come,...)is added to that blessing.]
On a Sabbath which is also Rosh Chodesh, a festival, or a CholHamo'ed, R'tzey is recited first, and then Ya'aleh v'yovo, for theSabbath is holier and a more frequent occurrence than these days.
11. A person who forgot and is unsure whether or not he recited gracemust recite the grace again if his appetite is satisfied. (For then,the obligation to recite grace is from the Torah itself.*) Similarly,a person who falls asleep in the midst of grace and does not know atwhich point he stopped must recite the entire grace again.
* {Deuteronomy 8:10 states: "When you shall be eat and be satisfied,you shall bless G-d, your Lord..." Thus, according to the Torahitself, the requirement to recite grace applies only when one haseaten to the point of satisfaction. Nevertheless, the Sages imposedthe obligation of reciting grace after eating a k'zayis.}
A women who is unsure of whether or not she recited grace does nothave to recite grace again.*
* {This law is based on the principle that it is questionable whethera woman's obligation to recite grace stems the Torah or the Rabbis.However, a woman should not be prevented from reciting grace if shedesires to do so (Mishnoh B'rurah 186:3).
12. The following laws apply if a person erred and omitted R'tzey onthe Sabbath or Ya'aleh v'yovo on a festival:
If he remembered before reciting G-d's name in the blessing BoruchAttoh Ado-noi boneh b'rachamov Yerushalayim. Amen, he should go backand recite R'tzey or Ya'aleh v'yovo and then repeat the phrase Uv'neyYerushalayim and complete the blessing.
If one remembers after mentioning G-d's name, one should conclude theblessing boneh b'rachamov Yerushalayim. Amen, and recite thefollowing :
On the Sabbath: Boruch Attoh A-d-o-n-o-i E-l-o-h-e-i-n-u Melechho'olom asher nosan yomim tovim l'amo Yisroel l'soson ul'simchoh, esyom chag - hazeh. Boruch Attoh A-d-o-n-o-i m'kadesh Yisroelv'haz'manim. (Blessed are You, G-d, our Lord, King of the Universe,Who has granted festivals to His nation, Israel, for happiness andrejoicing, [including] this festival - . Blessed are You, G-d whomakes holy Israel and the seasons.)
Should a festival fall on a Sabbath and a person forget both R'tzeyand Ya'aleh v'yovo, he should recite the following:
Boruch Attoh A-d-o-n-o-i E-l-h-e-i-n-u Melech asher nosan sabbososlimenuchoh l'amo Yisroel b'ahavoh, l'os ul'bris, v'yomim toviml'soson ul'simchoh, es yom chag - hazeh. Boruch Attoh Ado-noim'kadesh hashabbos v'Yisroel v'haz'manim. (Blessed are You, G-d, ourLord, King of the Universe, Who has granted Sabbaths for rest to Hisnation, Israel, as a sign and a covenant, and festivals for happinessand rejoincing, [including] this festival -. Blessed are You, G-d whomakes holy the Sabbath, Israel, and the seasons.)
On such an occasion, a person who recited R'tzey, but omitted Ya'alehv'yovo, should the following the practice mentioned above with regardto festivals. If he recited Ya'aleh v'yovo but omitted R'tzey, heshould follow the practice mentioned above with regard to theSabbath.
