(6) 6. If the 15th falls on Shabbat, we do not read the Megillah on Shabbat. Rather, we arrive early to read it on Friday and we collect money for gifts to the poor and distribute them on Friday. And on Shabbat, we take out two Torah scrolls and in the second we read "And Amalek came". We say Al HaNisim and we do not make a Purim feast until the day after Shabbat.

...When Purim falls out on Friday, they should have the meal in the morning because of honor for the Sabbath (Minhagim).

(2) 2. And likewise the cities which are visible to them even though they are not adjacent to them; for example, they are on a mountain. Or they are adjacent to them even though they are not visible to them; for example when they are in a valley. This is provided they are not farther than a mil. And Shushan, even though it was not surrounded by a wall from the days of Joshua, reads on the 15th [of Adar] since this is where the miracle occurred.

(2) 2. 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". RAMA: 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.

(12) [In a case of] one who was eating on the eve of Shabbat, and the day became sanctified upon him (Shabbat began) while he was in the midst of his meal: He should spread a tablecloth over his table, make Kiddush, finish his meal and then recite the Grace After the Meal. [And if] he was eating on Shabbat, and Shabbat went out while he was in the midst of his meal, he should finish his meal, wash his hands and recite the Grace After the Meal over a cup, and then recite Havdalah over it. And if he was in the midst of drinking, he should stop, recite Havdalah and then return to his drinking.

(18) 18. The Megillah [of Esther is read] on the 14th [of Adar in unwalled cities] and on the 15th [of Adar in waled cities], [and] one must make sure that [he is attending the Megillah reading among] a [congregation of at least] ten men. And if one cannot find [a congregation of] ten men, one may read it by himself. RAMA: It is uncertain if women are [legally counted as composing part of] a congregation of [at least] ten men [Hagahos Ashiri; Tur]. If [the Megillah] is read in a congregation [of at least ten men], and an individual happened to not hear the reading, he should read it on his own (even though ideally, one must seek a congregation of at least ten men), since [at least] it is being read in his city amongst a congregation [of at least ten men] [Beis Yosef in the name of Orach Chayim]. And when an individual (not amongst a community) reads it during the time [period when it is legally required], he must make a blessing (special blessing acknowledging the requirement of reading the Megillah) on it. [Beis Yosef]

(4) 4. It is forbidden to taste anything before one makes Kiddush [at night], even water. And even if one began eating while it was still day, he needs to stop eating, spread out a tablecloth [to set up the meal] and make Kiddush. And if they were drinking wine first, they only need to say the Bracha of Kiddush and not a Bracha on the wine. Afterward they will make a Bracha on the bread. And if he does not have wine, he can make Kiddush on bread, he need not make a Bracha on bread [because he has already been part of a meal where bread was eaten]. There are those who say that even if he makes a Bracha on wine, he also need not make a Bracha on the bread.
