סימן סא סעיף ב
צָרִיךְ לְבָרֵךְ בְּרָכָה זֹאת בִּפְנֵי עֲשָׂרָה, חוּץ מִמֶּנּוּ, וּשְׁנַיִם מֵהֶם יִהְיוּ תַּלְמִידֵי חֲכָמִים שֶׁעוֹסְקִים בַּהֲלָכוֹת, שֶׁנֶּאֱמַר, וִירוֹמְמוּהוּ בִּקְהַל עָם וּבְמוֹשַׁב זְקֵנִים יְהַלְלוּהוּ. וְאִם אֵינָם נִמְצָאִים לוֹ תַּלְמִידֵי חֲכָמִים, אֵינוֹ מְעַכֵּב. וְנוֹהֲגִין לְבָרֵךְ כְשֶׁעוֹלֶה לַתּוֹרָה, לְאַחַר שֶׁבֵּרַךְ בְּרָכָה אַחֲרוֹנָה. וּלְכַתְּחִלָּה אֵין לְאַחֲרָה יוֹתֵר מִשְּׁלֹשָׁה יָמִים. וְלָכֵן אִם נִצַּל בְּיוֹם בּ', יְבָרֵךְ מִיָּד בְּלֹא סֵפֶר תּוֹרָה, וְלֹא יַמְתִּין עַד יוֹם ה'. וְכֵן אִם הָיָה אָבֵל, שֶׁאֵינוֹ רַשַּׁאי לַעֲלוֹת לַתּוֹרָה, לֹא יַמְתִּין אֶלָּא יְבָרֵךְ מִיָּד. אַךְ יְבָרֵךְ מְעֻמָּד בִּפְנֵי עֲשָׂרָה כְּמוֹ שֶׁכָּתַבְתִּי. וּבְדִיעֲבַד אִם אֵחֵר יוֹתֵר מִשְּׁלֹשָׁה יָמִים, יָכוֹל לְבָרֵךְ גַּם אַחַר כָּךְ (רי"ט).
The berachah [Hagomeil] should be said in the presence of ten [male adults] besides the one who is saying the berachah.2According to Mishnah Berurah the one who is saying Hagomeil may be included in the quorum of ten [216: 6] Two of them should be scholars who are engaged in the study of Torah, as it is said: "Let them exalt Him in the assembly of the people and praise Him in the seat of the elders."3Psalms 107: 32. But if no scholars are present this should not deter him [from saying the berachah]. It is customary to say the berachah [Hagomeil] when called to the reading of the Torah after the concluding berachah. You should not intentionally delay [saying Hagomeil] longer than three days. Consequently, if you were saved [from danger] on Monday [after the Torah was read], you should say Hagomeil immediately without the Torah scroll, and not wait until [the next Torah reading on] Thursday. Likewise, if a person is a mourner, who may not be called to the Torah, he should not wait, but say [Hagomeil] immediately [after being saved from danger], but he should say it while standing4The berachah Hagomeil should always be said while you are standing, but if, unavoidably, you said it while sitting, you fulfilled your obligation. (Mishnah Berurah 219: 4) before ten [male adults], as mentioned above. If it so happened, that you did delay [saying Hagomeil] longer than three days, you may still say it afterwards.
