Q&A from the Bais HaVaad Halacha Hotline

Busy. Signal?

April 30, 2026

Q My neighbor in shul was davening Shmoneh Esrei audibly and incorrectly said “vesein tal umatar” in Iyar. Should I have interrupted my own Shmoneh Esrei to correct him?

A The Mishnah (Brachos 30b) famously teaches that one may not interrupt Shmoneh Esrei even if a king greets him or a nonvenomous snake is coiled around his heel. This ruling is codified in Shulchan Aruch (O.C. 104:1) and stands as a paradigm of the extreme stringency of interrupting the Amidah

The Mishnah Brurah (ibid. 1) clarifies that the prohibition extends beyond speaking to signaling. But a hand gesture is generally treated more leniently than speech. If it serves to eliminate an obstacle to kavanah—like motioning to quiet a noisy child— it is permitted (Mishnah Brurah ibid.). Similarly, a rav may signal the chazan to begin Chazaras Hashatz and not wait for him, if the chazan’s waiting would impair the rav’s kavanah.

In your case, you would be signaling not to protect your own concentration but to help another Jew daven properly. Does that justify a nonverbal hefsek?

R’ Shlomo Zalman Auerbach (Halichos Shlomo, Tfilah 8:6) rules that it does. R’ Moshe Feinstein (Igros Moshe O.C. 4:16) concurs and explains that legitimate tzarchei tfilah include someone else’s prayer. R’ Shlomo Zalman (see notes ibid.) says that even if your friend won’t get the message without words, you may not resort to speech. Although he will need to say Shmoneh Esrei again, his first one does not constitute brachos levatalah, so a verbal hefsek is not warranted.
