Molid
From Halachipedia
This article is okay. |
The prohibition of Molid is general in nature and has many applications. [1]
Crushing and melting ice
- One may not crush ice on Shabbat, but one may place ice into a cup of water and have it melt on its own [2]
- One may walk on ice or snow on Shabbat and it is not a concern of melting ice. [3]
- One may melt ice on shabbat if the water which comes out goes to waste. Therefore, ice can be disposed of in the sink, or one may cool a bottle with ice. [4]
- One may place ice into a cup of liquid but one shouldn’t accelerate the melting by pressing the ice. [5] According to Sephardim one may shake the cup even if that accelerates the melting. [6]
- One shouldn’t put ice in a cup in order for the ice to melt and drink the water. If one did so, it’s advisable not to use the water but it’s not forbidden. [7]
- One should not place ice in a cup and intend to drink it when it melts. [8]
- One should not have a frozen milk or juice container melt or thaw unless there's an important need for the liquid. [9]
- One may break ice cubes that are frozen together in an ice tray because one does not intend to produce water from the breaking.[10]

- ↑ Background
The gemara Shabbat 51b writes that one may not crush now but may place it into a glass on Shabbat. There are a few different approaches to why it would be prohibited to crush snow:- Rashba there explains that the prohibition is based on the prohibition of sechita (squeezing), that just as it is forbidden to squeeze fruit it is forbidden to squeeze ice.
- Rashi 51b “kdei” writes that you are being “molid” on Shabbat, and it is like a melacha. The Rosh 4:13 understands the sefer hateruma 234-235 as saying a similar idea
- The aforementioned Rashba quotes the sefer hateruma 234-235 understands that the problem is based on the muktzeh category of nolad. Since the result will be muktzeh since it is a newly created item, it would be prohibited.

Dovev Mesharim 1:55, Shevet Halevi 3:55 Chelkat Yaakov 2:98 also say not to make ice on Shabbat. The Shabbos Kitchen 177 footnote 22 quotes Or Hashabbos 4:107 in the name of Rav Moshe that you can make ice because it has no permanence. see also Tzitz Eliezer 6:34 and 8:12 as well as Minchat Yitzchak 8:24
