There are a few matters of note in this week's
"Halacha Summary
" email from the
shul that I would like to mention (in accordance with what the
Rebbe, shlit"a, has said on various occasions). The first is regarding the time by which
Shema must be recited.
In the email, it says, "According to the
Magen Avrohom, the day is reckoned from dawn until nightfall. According to the
Vilna Gaon, the day is reckoned from sunrise until sunset. Hence, the deadline for
Shema according to the
Magen Avrohom is earlier than that of the
Vilna Gaon. The custom is to follow the opinion of the
Vilna Gaon which gives a later deadline. It is praiseworthy to
daven with a
minyan that reaches
Shema before the deadline of the
Magen Avrohom."
