If a person is going to start davening and its so close to zman krias shma that he won’t make it if he says all of Psukei Dzimra, is it better to skip parts of Psukei Dzimra to make it in time, or should he instead say krias shma beforehand and then say all of Psukei Dzimra.
It is better to skip parts of Pesukei Dzimra, in order to say Kriyas Shema with the brachos. This is better than saying Kriyas Shema earlier by itself.
