“The gemara in Rosh Hashana is poshut telling us in the maskana of the gemara that safek deoraysa will be mechayev you to go somewhere which is a safek if you will be mekayem a mitzvah, even at teh cost of a vadai drabanan. And see the way the Mishna berura explains it in siman 595. About the ran, there is a lot to sasy about Rabbi Miller’s tayneh, but being that all the other mareh mekomos are clearly applicable I will not elaborate”.
I saw a discussion from 3 months ago about the Reb Chaim that a safek mitzvah is not ????.
This has always been my prime example what happens when not lomdanim get involved with PSAK. They end up embarrassing themselves. Ive seen this Ran etc quoted so often and it is a total error. Nothing to discuss. The briskers have a Mesora that if the fulfilling of a Mitzah one will still remain in a Matzav of Chiyuv it is useless. Therfor if one performs a Mitzvah in a way that he will still have to do it again because of ??? ??????? ?????? then he accomplished nothing. So if you have a ???? that was ??? ???, there is no point in taking it because ??? ??????? will tell you do it again. However if you are ????? if you are ???? in a ???? or could possibly fulfill it for sure (the case of ??? ????) then of course you have to do it (The radziner quotes someone that say you would be ???? but this in NOT the Reb Chaim) The Ran is talking about Bein Hashmeashos which is a ??? whether you are ???? and by taking it you will fulfill that requirement nothing else to do, no different from a tumtum who is ???? I hate to say it, but anyone quoting the Ran either totally missed Reb Chaim or is completely embarrassing himself.
