Arvit of the night of Pesach
Arvit of the night of Pesach
- One doesn’t need to wait to say Arvit after Tzet HaKochavim. 
- Sephardim have the custom of reciting Hodu LaHashem ki tov, chapter 107 of tehillim before reciting arvit. 
- In arvit of Pesach night, we conclude the beracha of hashikevenu like we do on Shabbat and not like we normally do on a weekday. 
- Many ashkenazim have the minhag to recite vayidaber Hashem et moadei Hashem el bnei yisrael before reciting the kaddish after the brachot of shema.  Some sephardim have the minhag to say ele moadei Hashem mikraei kodesh asher tikriu otam bimoadam, some have the minhag to say vayidaber Hashem et moadei Hashem el bnei yisrael, and some say both. 
If the first night falls on Shabbat
- If the first night of pesach falls out on shabbat, the perek of bameh madlikin is not read. 
- After hashkivenu those who usually add the pesukim of vishamru add it on this night as well. 
- The middle beracha of the shemonei esrei on yom tov that falls out on shabbat is mikadesh hashabbat viyisrael vihazmanim. 
- There is no Mein Sheva on a Friday night that falls out on the first night of Pesach. Some mekubalim have the practice to say it.
- As on the other yamim tovim, the middle beracha that we recite is mikadesh yisrael vihazmanim.  There is a discussion among the poskim if one concluded instead with just mikadesh yisrael if he nevertheless fulfilled his obligation. 
- Many have a minhag to recite hallel after the shemoneh esrei with a beracha on the first night of Pesach, as well as the second night of yom tov sheni shel galuyot.  Therefore, if one has the custom to recite it but is in a shul where they do not, he should nevertheless say it on his own. 
- Some poskim say say that even one who prays on his own should recite the hallel with a beracha. 
- The recitation of the Hallel in shul is because of the miracle of Hashem taking us out of Egypt and so it applies to women as well just like the other mitzvot of the night. It can be said even without a minyan before kiddush with a bracha. Some poskim disagree. 
- For those who allow saying arvit early on the night of the seder, the hallel in shul can also be said early.
- Many Ashkenazim however, didn't have this custom.  One who doesn't usually recite it, but finds himself in a shul where they do, should recite it along with them. 
- Chaim LeRosh (pg 40a; http://hebrewbooks.org/pdfpager.aspx?req=22746&st=&pgnum=80) says that Arvit must be said after Tzet. However Chazon Ovadyah (Pesach part 2 pg 5) argues. One shouldn’t delay especially considering the fact that S”A 472:1 rules that one should stop learning earlier so that you can start the meal early so that the children will be awake to ask questions.
- Kaf Hachayim 487:3
- Kaf Hachayim 487:1. see also Shulchan Aruch 267:3 and Mishna Brurah 267:8 for the differences in text
- Mishna berura 267:9. see however Maaseh Rav 67 that these pesukim that are customarily said before the kaddish aren't said as they may be considered a pause between geula and tefilla.
- see Kaf Hachayim 487:1 and Chazon Ovadia page 106
- Rama 270:2, Mishna Brurah 270:5, Kaf Hachayim 270:7-8
- Chazon Ovadia page 106. see above about the pesukim of vayidaber.
- Shulchan Aruch 487:1, Mishna Brurah 487:8
- Shulchan Aruch OC 487:1 writes that there's no Mein Sheva on Friday night which falls out the first night of Pesach. Mishna Brurah 487:9 explains that since it is a night protected from any danger there's no concern about those who are taking longer to daven. Rav Yitzchak Yosef explained how this is the correct minhag of Yerushalayim unlike the Rashash. But if they incorrectly started they should finish it. Kaf Hachaim 487:23 writes that the minhag of Izmir and Bet El shul in Yerushalayim was like the Rashash and they can continue to follow that practice since there's no safek brachot if there's a minhag.
- Shulchan Aruch 487:1.
- Mishna Brurah 487:2 says in the name of the eliya rabba and other achronim that he has not fulfilled his obligation. Chazon Ovadia page 106 however, writes that you have. see also Kaf Hachayim 487:17 who quotes poskim on both sides.
- Shulchan Aruch 487:4, Birkei Yosef 487:7, Kaf Hachayim 487:35, Chazon Ovadia page 109, Sh"t Yabia Omer 2:25 and 4:21. Yechave Daat 5:34 adds that even shuls that do not have the minhag should start it. Tur 473 writes that many places have the custom to recite hallel in order that they will not have to recite a beracha on the hallel during the seder. The Beit Yosef there says that this is in fact the minhag of the sepharadim based on Masechet Sofrim 20:9. According to Sefer Mikraei Kodesh (Hilchot Leil Haseder by Rabbi Moshe Harari) page 113 some yemenites have the minhag not to recite it with a beracha and some do not recite it at all.
- Chazon Ovadia page 111, Sh"t Yechave Daat 5:34, Kaf Hachayim 487:38-39
- Sh"t Yechave Daat 5:34 says that you should but quotes poskim who disagree.
- Yachava Daat 5:34, Yalkut Yosef Moadim page 382
- Moadim Uzmanim 7:179
- Yachava Daat 5:34
- Rama 487:4, Mishna Brurah 487:16. Moadim Uzmanim 3:260 and Kaf Hachayim 487:45 however, write that nowadays the minhag has become that even ashkenazim recite hallel with a beracha. Sefer Mikraei Kodesh (Hilchot Leil Haseder by Rabbi Moshe Harari) page 113 says that Rav Avraham Yitzchak Kook would make sure to go to a Chabad shul where they would recite hallel with a beracha on the first night of Pesach.
