Reply To: Chidushim on Daf Yomi

In SA O’CH 109,3 says that if one is in the middle of shmonei esrrei other than kedusha, he should stay quiet to listen to kedusha as שומע כעונה, hearing is like answering. This rule is also used when hearing the leining of the megilla, so they ask we must lein aloud from a megilla and he does not have these, so how can he be yotzei the mitzva of leining the megilla? The answer is, that it does not mean he is leining with his own mouth but ihis mouth is speaking with the voice of the baal korreh who has a megilla. But, he is speaking, so why is that not hafaek in the middle in of shmonei esrei?
They say that one who wants to do a mitzva can not be forced to do an aveira. We find a similar idea in Bava Metzia 96,2 איסווא לא ניחא ליה דלקני one does not want to acqure an issur e.g. chametz through kinyan chatzer.
