I have always heard that while we do not eat in the Sukkah while it rains, those of Chabad do. Why is this so? Found it on wikipedia too: Though the halakha doesn't obligate one to eat or sleep ...
If Lubavitch is careful not to eat or drink anything outside of the sukka, why does Lubavitch not sleep in the Sukka?
Shouldn't the obligation to sit in the Sukkah also fall into the category of Sefeika D'yoma? If so why do some not eat in the Sukkah on Shemini Atzeres?
