“Reb” Eliezer
My statement was that “it should also be noted that according to שלחן ערוך, you may not be able to daven later if you missed the zman במזיד.” [I assume this is the part of my post you refer to.]
Your response: “catch yourself, what you sayng is incorrect according to the interpretation of the O’CH 89 MB s’k 6.”
I’ll readily acknowledge that I misattributed the reference. The correct reference should be to the very Mishna Berura that you notated.
The Mishna Berura there says that if a person missed zman Tefila במזיד, it’s best for him to Daven בתורת נדבה (with a תנאי to cover the possible חיוב), since it is possible that he is no longer able to Daven the required Tefila.
This discussion is specifically about a person who missed zman Tefila במזיד and now wants to Daven before חצות. Please note that if he did not Daven before חצות he will not be allowed to Daven Mincha twice.
Also noteworthy is the fact that the Mishna Berura does not agree that a person who missed the zman can still Daven Shacharis during the half hour after Chatzos. B’dieved, he says that if you did, you should not Daven Mincha twice.
In a published Teshuva about your question, Rav Moshe Feinstein writes that it is not our responsibility to understand the actions of Gedolim, but that we must follow Shulchan Aruch.
