Let's read Tav Pei Alef (section reference) in Maran and the Shulchan Aruch to make sure we didn't leave anything. I'm reading Tav Pei Alef in Maran. Tav Pei Alef. Maran. Achar arba kosot eino rashai lishtot yayin ela mayim (After four cups, he may not drink wine, only water). Okay, we saw that: only water. We went into coffee; we went into sugar. Hagah (gloss): vechol hamashkin dinam keyayin (And all beverages have the status of wine). Okay. Mi shehu istanis, o ta'ev harbeh lishtot, yachol lishtot kos chamishi (One who is delicate or greatly desires to drink may drink a fifth cup). Wow.
Now you have to see the... Go back to the Aruch HaShulchan. I don't think we met Tav Pei Alef in Aruch HaShulchan. Look at Alef (first Hebrew letter). Kabbalah (received tradition), Kabbalah, Kabbalah, Kabbalah, Kabbalah, Kabbalah. A special fifth cup on Hodu laHashem (Give thanks to Hashem). But Rambam brings it. Where is Rambam? Fifth cup.
We know four cups; we've never heard of drinking a fifth cup, right? Some say only if you need to drink a fifth cup. Anybody need to drink a fifth cup? Yosef Tova'el B'Piut Elokeh Ano Chodesh Shabbat HaGadol. Like it's in some poem that Rabbi Ronan Shabbat HaGadol. Vezehu shekatav Rabbeinu haRema (And this is what Rabbeinu haRema wrote). Mi shehu istanis, o ta'ev harbeh lishtot, yachol lishtot kos chamishi (One who is delicate or greatly desires to drink may drink a fifth cup), ve'omer alav Hallel HaGadol (And recite the Great Hallel over it). Ach mi-yamenu lo shama'anu velo ra'inu nohagim ken (But in all our days we have not heard or seen this practiced). We never heard of it, Rabotai (my masters). We never heard of it.
Gimel (third Hebrew letter). Vezeh shekatav haRambam (And this is what the Rambam wrote), she'achar kach asur lishtot yayin ela mayim (That afterward it is forbidden to drink wine, only water). That's why, after the kosot or after the afikoman (final piece of matzah), you can only drink water. The only thing the Gemara says you can't eat is that the kusot is food. But the kusot is food. So you're not going to the Rosh. Drinking was never assur (forbidden). The Yaman Mishnah only said, yeah, wine, drink whatever you want. But the Gemara is like the Geonim, that even drinking is assur. And that's what Maran wrote, by the way. Look at what Maran wrote in Alef. After four cups of wine, there is no need to drink wine without water. Alef wrote in the name of his father, the son of Yosef, good knowledge. The one who wrote the rapes, the one who wrote all the Geonim. So it's the Geonim that Maran was supposed to follow. Rabbeinu Yonah piresh hata'am (explained the reason).
What's the reason why you can't drink anything after, or eat anything after, the afikoman? Because you have a man who has to work all night to make slime. Because you have a mitzvah (commandment) to stay up the whole night and talk about slime. You can do more than you have to because we want you to stay up to learn the whole night, and that's the... That's the irony that the poskim (halachic authorities) keep talking about. She won't know. Where does it say you have to stay up all night? And all classes says of all night Pesach, where everybody says you have to stay up all night? Most people don't stay up all night.
And some say the reason why you don't eat it is so you don't take the taste of the matzah (unleavened bread) out of your mouth. Some type of drink they had, and lemonade, is that right? Amazinga beer, some type of ginger drink, ginger water, mutar (permitted). And again, it's a little seltzer, and lemonade. Yeah, I told you, lemonade's okay. No lemonade, I heard that from the city. Mutar, what do you call it, Mike's Lemonade, what do they call it? Those are lemonade things, that's drinks, okay? That's a drink, I guess that's like a cider, yeah, apple, apple trunk, yeah. I read it, so I'm going to read the whole line. But don't drink if you're nothing, in order to ensure that no one is killed by the mazikim (harmful spirits).
