אין צריך לחזור. וכ"פ ב"ח ומט"מ ושל"ה דלא כלבוש שכתב שנוהגין לחזור דהרי בהג"מ כתב דא"צ והוא היה בקי במנהגים ובד"מ סימן תקפ"ב כתב כענין זה כתב הרשב"א בתשובה סי' ל"ה:
This is also the opinion of the Bach, Matah Moshe, and the Shelah and is against the Levush who writes that "the custom is to repeat (shemonah esrie)." This is an incorrect ruling as the Hagoes Maimonedes writes that you do not have to repeat and he was an expert in customs (so if the Levush was correct he wouldn't have ruled as such). The Darchie Moshe in siman 582 writes "in a similiar matter the Rashba rules so in his responsa work siman 35."
