אַאַמוּ"ר הָיָה מַדְלִיק נֵרוֹת חֲנוּכָּה בֵּין מִנְחָה לְמַעֲרִיבMy revered father, the Rebbe [Rashab], would kindle the Chanukah lights between the Afternoon Service and the Evening Service. וְלֹא הָיָה מְדַיֵּיק בְּפֶתַח שֶׁיִּהְיֶה מִדָּרוֹם לְצָפוֹן אוֹ מִמִּזְרָח לְמַעֲרָבHe was not particular about whether it was placed in the doorway from north to south or from east to west. הַנֵּרוֹת הַלָּלוּ — אַחַר הַדְלָקַת כָּל הַנֵּרוֹת[He would recite the hymn] HaNeiros Halalu after all the lights were kindled.וְהָיָה יוֹשֵׁב בְּסָמוּךְ לְהַנֵּרוֹת חֲצִי שָׁעָהHe would sit near the lights for half an hour [every evening], לְבַד מֵעֶרֶב שַׁבָּת קוֹדֶשׁ שֶׁלֹּא הָיָה מִתְעַכֵּב חֲצִי שָׁעָה —except for Friday afternoon when he would not wait that long. מְדַיֵּיק שֶׁיִּדְלְקוּ הַנֵּרוֹת חֲמִשִׁים מִינוּט לְכָל הַפָּחוֹתHe would see to it that the lights should burn for at least 50 minutes.מִנְחָה, נֵר חֲנוּכָּה, נֵר שַׁבָּת[On the eve of Shabbos during Chanukah, the sequence is:] the Afternoon Service; Chanukah lights; Shabbos candles.Text and Translation courtesy of Sichos in English
