Q. If I skip a major portion of the middle of the first brocha of kerias shema, in Sharcharis, I have I still fulfilled my obligation?
A. Horav Shlomo Miller Shlit"a opinion is that if you said the beginning of the brocho (Yotzer Or) properly and the end (from LoE-l until the end) correctly, you may have fulfilled your obligation, and you should not repeat it. You should try to find someone who has not yet recited this brocho and ask him to have the intention to be “moitze” you when he says it and you listen.
