Can we have hazaores hashatz for Musaf, if the tenth left the room before Musaf began, and then returns at the end?
In shacharis, the rational for this is based on there being someone who has not heard barchu, the kedushah, etc.., see Orech Chaim 69.
Can we apply this same din and the conditions and reasoning brought there, for Musaf?
Please use sources in Shulchan Aruch and Poskim.
