Question: I saw in some siddurim that the last stanza of the piyut of the Arizal for the Shabbat day meal (יְדַי אַסְחֵי אָנָא, לְגַבֵּי חַד מָאנָא, לְסִטְרָא אַחְרִינָא, דְּלֵית בֵּהּ מַמָּשָׁא. אֲזַמֵּן בִּתְלָתָא, בְּכַסָּא דְבִרְכָתָא, לְעִלַּת עִלָּתָא, עֲתִיקָא קַדִּישָׁא.) should be recited prior to washing mayim acharonim:
Should this be recited only during the Shabbat day meal, or also during the other two Shabbat meals as well?
Answer:
