הלכות קריאת שמע

פַּעֲמַיִם בְּכָל יוֹם קוֹרְאִין קְרִיאַת שְׁמַע, בָּעֶרֶב וּבַבֹּקֶר. שֶׁנֶּאֱמַר (דברים ו ז) ״וּבְשָׁכְבְּךָ וּבְקוּמֶךָ״ בְּשָׁעָה שֶׁדֶּרֶךְ בְּנֵי אָדָם שׁוֹכְבִין וְזֶה הוּא לַיְלָה. וּבְשָׁעָה שֶׁדֶּרֶךְ בְּנֵי אָדָם עוֹמְדִין וְזֶה הוּא יוֹם:

The Shema is read twice every day,—in the evening and in the morning, as it is said, "and when thou liest down and when thou risest up" (Deuteronomy 6:7), the phrases in this text meaning at the time when men are lying down, that is, at night, and at the time when they have risen, that is, by day.

וּמַה הוּא קוֹרֵא, שְׁלֹשָׁה פָּרָשִׁיּוֹת. אֵלּוּ הֵן (דברים ו ד) ״שְׁמַע״ (דברים יא יג) ״וְהָיָה אִם שָׁמֹעַ״ (במדבר טו לז) ״וַיֹּאמֶר״. וּמַקְדִּימִין לִקְרוֹת פָּרָשַׁת שְׁמַע מִפְּנֵי שֶׁיֵּשׁ בָּהּ יִחוּד הַשֵּׁם וְאַהֲבָתוֹ וְתַלְמוּדוֹ שֶׁהוּא הָעִקָּר הַגָּדוֹל שֶׁהַכּל תָּלוּי בּוֹ. וְאַחֲרֶיהָ וְהָיָה אִם שָׁמֹעַ שֶׁיֵּשׁ בָּהּ צִוּוּי עַל (זְכִירַת) שְׁאָר כָּל הַמִּצְוֹת. וְאַחַר כָּךְ פָּרָשַׁת (במדבר טו לח) ״צִיצִית״ שֶׁגַּם הִיא יֵשׁ בָּהּ צִוּוּי זְכִירַת כָּל הַמִּצְוֹת:

What does one read? Three sections as follows: the section beginning, "Hear, O Israel" (Deuteronomy 6:4-9); that commencing, "And it shall come to pass" (Deuteronomy 11:13-21); and that commencing, "And the Lord spoke" (Numbers 15:37-41). The section beginning, "Hear, O Israel" is recited first, because it sets forth the duties of acknowledging the Unity of God, loving Him, and studying His words. This is the great and essential matter on which all depends. Then, the passage beginning, "And it shall come to pass" is read, this containing a charge to fulfill all the other commandments. Finally the section concerning Fringes is read, as it also contains a charge to remember all the commandments.
