Is there any opinions that hold that one can daven mincha at least b’dieved during the week until the tzeis that he holds is the end of shabbos. Meaning if one holds “42” then he can daven mincha bdieved on a monday night until 42 minutes after the shkiya. Specifically for somebody who does not hold of Rabbeinu Tam. thank you!!!
If someone is meikel to finish shabbos at 42, then he holds that it is considerd surely night at that point. Then he can not daven mincha then.
