Baruch Hashem l’Olam
Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. If someone is in the middle of the long blessing “Baruch Hashem l’olam” that is recited right before maariv shemoneh esrei, is he allowed to say “amen” to the chazan when the chazan says the bracha “Baruch atah Hashem, Shomer amo Yisrael l’ad,” that is said before the “Baruch Hashem l’olam” long bracha? Thanks.
