What is the source that Tefillah overrides bittul Torah? Thanks.
Answer:
The Gemara writes that we have to stop learning for the sake of prayer – with the exception of those whose “profession is their Torah study” – which does not apply to us (who waste plenty of time, even if occupied in full-time learning).
Best wishes.
