Shemonah Esrei in the Middle of the Hagadah

Sefer Admorei Belz (Chelek 3, page 206) relates that the minhag in Belz was that after the Rebbe concluded his Seder, he would go out to the streets to hear how the local Yidden were conducting their Seders.

One year, Rav Shalom of Belz zy”a and his gabbai, R’ Elimelech, heard a man make the bracha of “Ga’al Yisroel”, and continuing with the tefillah of Shemonah Esrei. The gabbai laughed but the Rebbe said, “This man accomplished a lot with this tefillah. He has no children but he will now have a baby!”
