Halocho #72 - Three-fold Purim

This year Purim is on Friday (21 March) and Shushan-Purim is on Shabbos, so cities that celebrate Shushan-Purim - like Jerusalem and Shushan (Susa, Iran) - will celebrate in 3 parts: 1. Friday:

• Megila reading is on Thursday night and Friday morning, like everybody else
• Matonos L'evyonim is given to the needy on Friday.

2. Shabbos:

• Al-Hanisim is added to Bircas Hamozon and the Amida.
• The Torah Reading for Purim (Shmos 17:8-16) is read as Maftir. (The same Haftoro is read as the previous week - Shmuel-1 Ch. 15.)
• One should learn some Halochos of Purim.

3. Sunday:

• Mishloach Monos is sent.
• The Purim feast is eaten.

This is the opinion of the Shulchan Oruch. Some people also do #3 on Shabbos. Others send Mishloach Monos on Friday. Source: Shulchan Oruch, Orach Chaim 688:6, Mishna Brura ibid. Shmos 17:8-16 8 : Then came Amolek, and fought with Israel in Rephidim. 9 : And Moshe said to Joshua: "Choose men, and go fight with Amlek: tomorrow I will stand on the top of the hill with the rod of G-d in my hand". 10 : So Joshua did as Moshe had said to him, and fought with Amolek: and Moshe, Aaron, and Chur went up to the top of the hill. 11 : And it came to pass, when Moshe held up his hand, that Israel prevailed: and when he let down his hand, Amolek prevailed. 12 : But Moshe's hands were heavy; and they took a stone, and put it under him, and he sat thereon; and Aaron and Chur supported up his hands, the one on the one side, and the other on the other side; and his hands were steady until the going down of the sun. 13 : And Joshua weakened Amolek and his people with the the sword. 14 : And the Hashem said to Moshe: "Write this for a memorial in the book, and rehearse it in the ears of Joshua: for I will utterly wipe out the remembrance of Amolek from under heaven. 15 : And Moshe built an altar, and called the name of it "Hashem did miracles": 16 : And he said, "Because the Hashem has sworn that Hashem will have war with Amolek from generation to generation."
