הַגָּה: מִצְוָה לְהַרְבּוֹת בִּסְעֻדַּת פּוּרִים (טוּר); וּבִסְעֻדָּה אַחַת יוֹצְאִים (מָרְדְּכַי ספ"ק). סְעֻדַּת פּוּרִים שֶׁעֲשָׂאָהּ בַּלַּיְלָה, לֹא יָצָא יְדֵי חוֹבָתוֹ. הַגָּה: וּמִכָּל מָקוֹם גַּם בַּלַּיְלָה יִשְׂמַח וְיַרְבֶּה קְצָת בִּסְעֻדָּה. (תְּשׁוּבַת מהרי"ו).

Laws of Purim meal. Containing 4 paragraphs Rema: It is a mitzvah to have many feasts during Purim (Tur), but one fulfills his obligation with only one feast (Mordechai) One who does the Purim meal at night does not fulfill his obligation. Rema: Nevertheless, one should be happy and add more during his meal even at night (Teshuvat Mahariv).

Se’if 2ב׳

חַיָּב אִינִישׁ לְבַסוֹמֵי בְּפוּרַיָּא עַד דְּלֹא יָדַע בֵּין אָרוּר הָמָן לְבָרוּךְ מָרְדְּכַי. הַגָּה: וְיֵשׁ אוֹמְרִים דְּאֵינוֹ צָרִיךְ לְהִשְׁתַּכֵּר כָּל כָּךְ, אֶלָּא שֶׁיִּשְׁתֶּה יוֹתֵר מִלִּמּוּדוֹ (כָּל בּוֹ) וְיִישַׁן, וּמִתּוֹךְ שֶׁיָּשֵׁן אֵינוֹ יוֹדֵעַ בֵּין אָרוּר הָמָן לְבָרוּךְ מָרְדְּכַי. (מַהֲרִי"ל). וְאֶחָד הַמַּרְבֶּה וְאֶחָד הַמַּמְעִיט, וּבִלְבַד שֶׁיְּכַוֵּן לִבּוֹ לַשָּׁמַיִם. וְאֵין לְהִתְעַנּוֹת בְּפוּרִים, מִלְּבַד תַּעֲנִית חֲלוֹם, וְעַיֵּן לְעֵיל סִימָן תקס"ח וְסִימָן תק"ע. יֵשׁ שֶׁנָּהֲגוּ לִלְבֹּשׁ בִּגְדֵי שַׁבָּת וְיוֹם טוֹב בְּפוּרִים, וְכֵן נָכוֹן (מַהֲרִי"ל); וְנוֹהֲגִים לַעֲשׂוֹת סְעֻדַּת פּוּרִים לְאַחַר מִנְחָה, וְעַרְבִית יִתְפַּלְּלוּ בַּלַּיְלָה. וּמִתְפַּלְּלִים מִנְחָה תְּחִלָּה בְּעוֹד הַיּוֹם גָּדוֹל; וְרֹב הַסְּעֻדָּה צְרִיכָה לִהְיוֹת בַּיּוֹם (מִנְהָגִים), וְלֹא כְּמוֹ שֶׁנּוֹהֲגִין לְהַתְחִיל סָמוּךְ לָעֶרֶב וְעִקַּר הַסְּעֻדָּה הוּא לֵיל ט"ו. וּכְשֶׁחָל פּוּרִים בְּיוֹם שִׁשִּׁי, יַעֲשׂוּ הַסְּעֻדָּה בְּשַׁחֲרִית, מִשּׁוּם כְּבוֹד שַׁבָּת (מִנְהָגִים); וּמִי שֶׁרוֹצֶה לַעֲשׂוֹתָהּ תָּמִיד בְּשַׁחֲרִית, הָרְשׁוּת בְּיָדוֹ (ת"ה). יֵשׁ אוֹמְרִים שֶׁיֵּשׁ לֶאֱכֹל מַאֲכַל זֵרְעוֹנִים בְּפוּרִים, זֵכֶר לַזֵּרְעוֹנִים שֶׁאָכַל דָּנִיּאֵל וַחֲבֵרָיו בְּבָבֶל (כָּל בּוֹ). טוֹב לַעֲסֹק מְעַט בַּתּוֹרָה קֹדֶם שֶׁיַּתְחִיל הַסְּעֻדָּה, וְסֶמֶךְ לַדָּבָר: לַיְּהוּדִים הָיְתָה אוֹרָה וְשִׂמְחָה (אֶסְתֵּר ח, טז) וְדַרְשִׁינָן: אוֹרָה, זוֹ תּוֹרָה (מהרי"ב). וְחַיָּב בְּמִשְׁתֶּה וְשִׂמְחָה קְצָת בִּשְׁנֵי יָמִים, י"ד וְט"ו, (מִנְהָגִים) וְכֵן נָהֲגוּ. וְיֵשׁ אוֹמְרִים דְאִם הִזִּיק אֶחָד אֶת חֲבֵרוֹ מִכֹּחַ שִׂמְחַת פּוּרִים, פָּטוּר מִלְּשַׁלֵּם. (ת"ה סִימָן ק"י). וְעַיֵּן בח"מ בְּדִינֵי נְזִיקִין.

One is obligated to be intoxicated on Purim to the point where he does not know [the difference] between "accursed is Haman" and "blessed is Mordechai". Rema: Some say it is not necessary to become drunk so much, but rather to drink more than he is used to (Kol Bo), and to fall asleep, and while he sleeps he does not know [the difference] between "accursed is Haman" and "blessed is Mordechai" (Maharil). [There is no difference on Purim] between one who has more and one who has less, as long as his heart is directed to heaven. One should not fast on Purim, except for a fast for a [bad] dream, and see earlier Siman 568 and Siman 570. There are those who have the custom to dress in Shabbat/Yom Tov clothes on Purim, and that is correct (Maharil). We have the custom to make the Purim meal after the afternoon prayer, and pray the evening prayer at night. We pray the afternoon prayer while most of the day remains, and most of the meal needs to be during the day (Minhagim). And it should not be like those who have the custom to start close to evening, and most of the meal happens during the night of the 15th. When Purim falls out on Friday, they should have the meal in the morning because of honor for the Sabbath (Minhagim). And one who wants to [have his meal] every [Purim] in the morning is allowed to (T"H). Some say that there is [significance] to eating seeds on Purim as a remembrance for the seeds that Daniel and his friends ate in Babylonia (Kol Bo). It is good to delve a bit in Torah before one begins the meal, and a support for that is (Esther 8:16) "The Jews had light and happiness...", which we learn out "radiance" - that's Torah (Mahariv). One is obligated to drink a little and be a little happy on two days, the 14th and the 15th (Minhagim), and so is the custom. And some say that if one causes damage to his fellow through his happiness on Purim, he is exempt from restitution (Terumat HaDeshen, Part I 110). And see Terumat HaDeshen Laws of Damages.

Se’if 3ג׳

אוֹמֵר עַל הַנִּסִים בְּבִרְכַּת הַמָּזוֹן בְּבִרְכַּת הָאָרֶץ; וְאִם הִתְחִיל סְעוּדָתוֹ בַּיּוֹם וּמָשְׁכָה עַד הַלַּיְלָה, אוֹמֵר: עַל הַנִּסִים, דְּבָתַר תְּחִלַּת סְעֻדָּה אַזְלִינָן; וְיֵשׁ מִי שֶׁאוֹמֵר שֶׁאֵין לְאָמְרוֹ, וְנוֹהֲגִין כִּסְבָרָא רִאשׁוֹנָה.

One says "Al hanisim" in the Grace After Meals during the blessing of the land ["Nodeh"]. And if one started his meal during the day, and extended it into the night, he [still] says "al hanisim", for we follow the [status of] the beginning of the meal. And some say one should not say it. (And we have the custom like the first opinion).
