If one is in middle of Shemoneh Esrei (which is the only part of Tefillah, I could think of where there might be a problem), and there is a life to be saved, is he/she allowed to interrupt the Tefillah in order to go save the life?
A famous halachic rule of thumb:
If someone has to ask his rabbi on questions of ordinary halacha (not murder or the like) vs. any matter of life or limb, shame on the person asking (duh, go save a life!), and shame on the rabbi who should have made that abundantly clear long ago.
So let's get this straight. If a question comes up about violating mitzva X vs. saving life or limb, ask yourself the following four questions about mitzva X:
- Is it murder?
- Is it worshipping idols?
- Is it a major sexual violation, such as adultery or incest?
- Is it giving in to mass attempts to stamp out Judaism?
If you've answered "no" to all four of these questions, hang up the phone and dial 911 (or do whatever else needs to be done).
Are we clear here?
I heard a hidush on the name of rav ovadia, in case someone is doing shemona esre by heart and in the middle can't remember some part, if there's no sidur in reach he can walk get the sidur, go back to his place and continue, since leaving the place is miderabanan and beracha levatala is mideoraita.
in this case I think you could leave your place do whatever necessary, go back and continue. all of course if you didn't speak. if you did speak that would be more complicated.
also I don't know if asheknezim poskim if beracha levatala is deoraita and if it would make a difference
