Se’if 1א׳
נָשִׁים וַעֲבָדִים פְּטוּרִים מִקְּרִיאַת שְׁמַע מִפְּנֵי שֶׁהוּא מִצְוַת עֲשֵׂה שֶׁהַזְּמַן גְּרָמָא. וְנָכוֹן הוּא לְלַמְּדָם שֶׁיְּקַבְּלוּ עֲלֵיהֶן עֹל מַלְכוּת שָׁמַיִם: הַגָּה: וְיִקְרְאוּ לְפָחוֹת פָּסוּק רִאשׁוֹן (בֵּית יוֹסֵף בְּשֵׁם אֹהֶל מוֹעֵד).
Who Are Exempt From the Recitation of the Sh'ma, Containing 5 S'ifim Women and slaves are exempt from the Recitation of the Sh'ma because it is a positive commandment that is time-dependent, and it is proper to teach them that they should accept upon themselves the yoke of the Kingdom of Heaven. Rema: And they should recite at least the first verse (Beit Yosef in the name of Ohel Moed)
Se’if 2ב׳
קְטַנִּים פְּטוּרִים לְרַבֵּנוּ תָּם כְּשֶׁלֹּא הִגִּיעוּ לְחִנּוּךְ, וּלְרַשִׁ"י אֲפִלּוּ הִגִּיעוּ לְחִנּוּךְ, מִפְּנֵי שֶׁאֵינוֹ מָצוּי אֶצְלוֹ בִּזְמַן קְרִיאַת שְׁמַע בָּעֶרֶב, וְיָשֵׁן הוּא בַּבֹּקֶר, וְרָאוּי לִנְהֹג כְּרַבֵּנוּ תָּם.
Minors are exempt according to Rabbeinu Tam - when they have not reached [the age of] education; and according to Rashi, even when they have reached [the age of] education because he is not usually with him (i.e. the father) at the time of the Recitation of the Sh'ma in the evening and he (i.e. the child) sleeps in the morning. And it is proper to act according to Rabbeinu Tam.
Se’if 3ג׳
הַכּוֹנֵס אֶת הַבְּתוּלָה פָּטוּר מִקְּרִיאַת שְׁמַע ג' יָמִים, אִם לֹא עָשָׂה מַעֲשֶׂה, מִפְּנֵי שֶׁהוּא טָרוּד טִרְדַּת מִצְוָה. וְהָנֵי מִלֵּי בִּזְמַן הָרִאשׁוֹנִים, אֲבָל עַכְשָׁו שֶׁגַּם שְׁאָר בְּנֵי אָדָם אֵינָם מְכַוְּנִים כָּרָאוּי, גַּם הַכּוֹנֵס אֶת הַבְּתוּלָה קוֹרֵא: הַגָּה: וע"ל סי' צ"ט אִם שִׁכּוֹר יִקְרָא קְרִיאַת שְׁמַע.
He who consummates a marriage with a virgin is exempt from the Recitation of the Sh'ma for three days if he did not do "the act" (marital relations) because he is anxious due to the anxiety of the commandment [of marital relations]. And this was the case only in the time of the early ones, but nowadays, when also the rest of the people are not able to have proper focus [for the Sh'ma], one who consummates a marriage with a virgin also recites [the Sh'ma]. Rema: See also Siman 99 [regarding] if one who is drunk should recite the Recitation of the Sh'ma.
